it truly is

I haven't tried the other games, so I don't know what features are in them, but there are a number of things I'd like to see in the next Fish Tycoon.
* More expanded genetics tree
* Some kind of genetics tracking utility (either automatic, or manually entering genetics as they are discovered.)
* Ability to exchange fish to other players/games in the same program
* More tanks, more different supplies, even more fish varieties.
