I have some intuition telling me that gruntz lovers will also love this game. It's a simulation game brought to life by Maxis, Electronic Arts. Basically, it's the motherload of simulation games because you simulate everything. You design and create how you want your entire universe to be. From designing your own unique cells to creatures to tribes to civilizations to intergalactic space federations. Yes, everything is modifiable. Furthermore, you can sculpt planets, colouring and shaping it to your will and then fill out its ecosystem with creatures you designed.
This game was rated as one of the technological innovations of 2008. One of the reasons for this is that the game offers a new system that involves complex and random calculations (or pseudo-random if you know anything about computers) to generate the creature you've designed and make it move in all the ways that appear life-like (emotions, dancing etc)

NOTE: don't even think about creating the walking phallus monster. Maxis has opted opted to ban all em.. edgy creations posted on the net. (what you create while offline however, is completely up to you)
