The traffic to my blog from my first Fishville post has been staggering.  How can I resist?  That’s right, it’s time for Yet Another Fishville Post (YAFP).  Come on, you know you want to read more…

I’ve been a little surprised to see how few accurate blog posts exist out on the web that break down the profit & experience for Fishville.  Based on comments to my original post, I made some mistakes.  As a result, I’m posting this follow up to help address the most common concerns:

• What about Level 5 (and 6 and 7…). I classify my charts based on the completion of levels, which is a little confusing because in Fishville, your fish is “Level 1” until it completes the level, and then it is Level 2, etc.  As a result, you don’t get the “Level 1” experience until your fish reaches Level 2.  Confusing.  Even more confusing, after completing Level 4, your fish can continue to go up levels… it just won’t be worth anything more.  As a result, I ignore all levels above 4.
• Why doesn’t my experience number match yours? It’s because I’m including the experience you get from dropping the egg in the tank, not just the experience you get from harvesting.
• Level 4 doesn’t take the same time as the other levels. Oops.  This is correct.  I still don’t have accurate info on whether the “Level 4” time is the same for all fish (2 days) or different.  For this post, I use the 2 day number, which changes the economics considerably.  (Hint: It’s not worth your time to ever let this happen)
• Can you post a Google Doc of all your tables & charts? See the end of this post.  First time for everything.

To recap, here are the assumptions for my tables & charts:

1. I assume harvesting & buying fish is instantaneous. Yes, I know its not.  Fodder for a future post.
2. All profits are calculated per fish. Same with experience
3. Total Experience = Experience from dropping egg + Experience from the level(s) of growth
4. Total Profit = Revenue from harvesting the fist – Cost of the egg

In my last post, I described how your “profit per minute” increases with levels, but your “experience per minute” falls with levels.  A lot of people didn’t understand this, so I decided to try some charts to illustrate.

Here is a chart I made in Google Docs showing the effect of increasing levels on Profit / Minute.  Because there is a fixed cost to buying a new fish, the linear increase in profit per level helps your profit / minute.  Of course, it falls off a cliff once you hit Level 4, and it takes up to 2 days to complete.

This means that, from a profit per minute perspective, it’s better to let your fish grow to complete Level 1, Level 2, and Level 3 before harvesting.

But there is a catch.  Because you get XP every time to buy an egg, the effect on experience points per minute is the opposite.  Every level you go, your experience points per minute drops!  See this chart to visualize:

Based on the comments to my original blog post, it’s very obvious that most players continue to ignore the experience points you get for dropping an egg in your tank – choosing instead to focus only on the experience points you get when you harvest the fish.  Big mistake, because this leads you to keep fish around too long.

Since my last post, I’ve also been able to complete my tables for all current fish.

Here is the profit table for Level 1 profits:

Here is the experience table for Level 1 experience.  Note that I included the experience you get for dropping the egg, as well as the total experience you get for completing level 1.  Remember, Total = Dropping Egg + Level XP:

As promised, here is a link to the Google Doc with all my tables and charts.  Please post additional info, corrections, or data in the comments below.

• Fishville Economics: Points, Experience & Levels Part 3

My Zynga addiction clearly knows no bounds.  Last week, Zynga launched a new game called Fishville, and clearly at this point I have no ability to resist any new Zynga game.

Fishville has a deceptively simple frame:  you have a fish tank, and you buy fish eggs for it.  The fish hatch, you feed them, and then when they are fully grown, you sell them for profit.

What I’ve found most interesting about the game is the new dimensions they are exploring in the economics of the game.  Fishville adds a couple distinguishing twists versus Farmville or Café World:

1. Multiple Tanks. How many people wish they had more than one farm in Farmville?  In Fishville, Zynga has two types of expansion – the ability to put more fish in a single tank and the ability to buy new tanks.  This may not seem relevant from a structural standpoint – after all whether you add 20 fish to one tank or 10 to 2 tanks shouldn’t matter – but it should create a new dynamic around buying virtual goods to decorate different tanks.
2. Harvest Levels. This is the real twist to the economics.  Fish grow up in stages, up to four levels.  The revenue in coins and the experience you get goes up linearly with each level.  So if you have a 4 hour fish, you can harvest them at 4 hours at Level 1, or 16 hours at Level 4.  You still have to feed them or they die (similar to withering crops in Farmville), but you don’t need to “replant”.

The Harvest Levels have the most impact on the game economics.  In financial terms, each fish now has a fixed cost and a variable cost, as well as a fixed experience pay-off and variable experience pay-off.

For example, let’s take the Mini Dart Goby, the first fish.

The Goby costs 7 coins for an egg.  That’s a fixed cost.  If you grow it to Level 1, you’ll get 18 coins, for a profit of 11 coins.  Easy, right?  Hold on.  If you wait until Level 4, you’ll get 72 coins over that same 7 coin cost, for a profit of 65 coins.

The fixed cost means that your “profitability” or “profit / minute” goes up the longer you wait to harvest.

Seems like a no-brainer to wait until Level 4?  Not so fast.

With Experience Points, the math works in reverse.

The Mini Dart Goby gives you 2 XP for dropping the egg.  At Level 1, you’ll get 8 XP, for a total of 10 XP.  But if you wait until Level 4, you’ll get 32 XP, for a total of 34 XP of the time period.  In this case, your “XP / Minute” goes down the longer you wait to harvest.

It gets even harder.

You can harvest a fish in-between levels… but you don’t get any credit for the time between levels.  So if you are half-way between levels, your “profit / minute” and “experience / minute” will be terrible.  In fact, the math says you need to harvest at level boundaries pretty closely.  (I think in a future blog post, I’ll graph this.)

For now, here are some tables I’ve made for the fish I have data on.  Unfortunately, this game is so new, I can’t find any guides online with data for all fish.  Special thanks to Erin Hoffmann, who serves as both data provider and my toughest competitor in Fishville.

The most interesting aspect to these tables is that while the profitability / minute rises for each level, Zynga has kept the fixed costs proportional enough that the ranking of the fish does not change significantly between 1 level or 4 levels.

Here is the profitability of different fish at Level 1:

Here is the profitability of different fish at Level 4:

Here is the experience productivity of different fish at Level 1:

Here is the experience productivity of different fish at Level 4:

If you’d like to help, I’m missing data for the following fish:

• Blue Damsel
• Inland Silverside
• Pajama Cardinal
• Longnose Hawkfish
• Annularis Angelfish
• Blue Spot Grouper
• Blue Hippo Tang
• Bartlett Anthias

For each, please leave a comment with:

• XP / Egg
• Revenue / Level
• XP / Level
• Minutes / Level

Hope this helps the new Fishville players out there.  Enjoy.

Update (11/14/2009): New blog post coming tomorrow, with updated tables and new info.  Also, fixing the issue around the whole “Level 4/Adult” confusion, and publishing a Google Doc to help others benefit from the raw data.  I’m still finding that people are ignoring the XP from the dropping of the egg, and only focusing on the XP from harvesting, so I’ll update tables to make that more clear.
