Is mixed American/British spelling a big deal in game writing?

Snarky, thanks for bringing that up, it's a good point.

In my game, English isn't as much "English", as it is a universal language that people can understand. I've tried to avoid as many colloqualisms, slang expressions and specific regional features as much as possible, to prevent people from reacting on something being out of place or character.

I've got a lot of confidence when it comes to producing formal English, but I'm really bad at capturing or emulating colloquial, natural speech, so I won't even try my hands at it. I guess this is probably reflected in the bookish tone of my daily posts here in the forum.

One thing I hate is when certain nationalities, especially Asians and Germans I guess - no offence anyone - create games or comics or even speak IRL and try so darn hard to sound American it just gets silly. There are certain types of exchange students I met during my student years that always spoke really bad English, but made sure to insert "ain't" and "my bad" and "whatnot" etc exactly everywhere, in hope of sounding American.
