Some more to add to the list:
Thou Shall Use Fewer Cutscenes
Please devs, stop with the fucking cutscenes. MGS, you're especially guilty of this. If you can't tell the story in-game properly, then at least make the cutscenes brief, not a fucking hour and a half, or at least make them interesting. Hideo Kojima, you could learn a get an editor.
Thou Shall Create Good AI
Maybe it's me, but when games from the past generation display better AI programming on both side of the coin, we have problems. I want teammates who can actually display some intelligence for a change. I want enemies who can actually put up a fight for a change. More importantly, I want escort AI that understands NOT to run headlong into the MG nests & try to stop bullets with the bridge of their nose.
Thou Shall Have Split-Screen Compatibility
Console devs, stop neglecting split screen just for more money or for online features. There still exist people who like to play split-screen for shits & giggles. Don't neglect something like that.
