So this is interesting... I use a mouse left handed, and am pretty good at first person shooters, but BioShock won't let me set my normal movement keys because one is not changable.. so I decide to shift my movement keys one to the left.. and one of those keys is not changable.
WTF?
Instead of WASD, I use IJKL --except in this game-- which is the only game that has ever made this an issue. I tried using UHJK, but it won't let me do that, either.
That's freakin' awesome.
