This isn't meant for any particular game [IDEA: Cell Types]:
The basic idea goes a little like this: you get to choose a type of cell you want to play as and depending on what you choose, you will have different stats at any point in the game. Here are 2 examples:
Decay: Slow at low mass but fast at big mass
Autosplit mass: 19K
Virus Sustainability: Very low. When hit is very sporadic.
Speed: Faster than average at all masses.
Split speed: Faster than average at all masses.
Mass tick speed?: Slightly higher than average.
W speed: Faster than average.
STE: 20% more (lower than average)
Merge timer: faster than average
Decay: Fast at small mass slow at big mass
Autosplit mass: 27.5K
Virus Sustainability: Very high, when it keeps big pieces
Speed: Slower than average at all masses.
Split speed: Slower than average at all masses.
Mass tick speed?: Slightly lower than average.
W speed: Slower than average.
STE: 26% more (higher than average)
Merge timer: slower than average
Note that these are just rough ideas. You can also add types that are in between these 2 or have some of both (get creative). Also, this idea is probably best in a team gamemode of about 3 or 4 people per team.
This will most likely never happen cuz most of this is calculated server-side, but still interesting nonetheless.
