This game is gonna explode.. soon

[CD Set]

If the big game makers get too worried they will just buy out FG.
If not, and FG does end up with a mega hit, then FG will most likely start to make games to try and please everybody. Xbox, Playstation, age ratings etc.
If that happens the next game will be more professionally done and take it's place in the -just-like-the-others category.
Only a few of us will lose out and so it won't really matter in the long term.

Actually, I think the opposite would apply. If Frictional were to receive lots of compensation and become practically independent economically, they could finally create the game that they actually want to create, with the money they have at the disposal (and I think it's fairly obvious that they do want to create original and creative content).

As it stands right now, my guess would be that they would be more prone to create a "lackluster standard game" if they didn't earn much from Amnesia, as they are then forced to create a less niched game to appeal to the masses (to survive as a company at all.)
