Control scheme 1.2 (aka Solitaire) is the only way to play GE/Perfect Dark. It makes it like WASD+mouse controls (C buttons for movement, analog for aim).
For whatever reason enough haven't tried it so the defaults of C buttons for aim obvs seem wack. Though I'd imagine for modern ports they've changed it to map to analog sticks now (one would hope
).
Perfect Dark improved upon GE in every way except for the vibe/aesthetic.
