Oh my god. No pissing match going on here. I even said that I was probably wrong! I was pretty much as polite as i could possibly be. I admit my post was wrong in one area: it was off-topic. Perhaps Marathon wasn't the first game to feature dual-wielding, but it appears to me that it was the one that influenced the later games to include it. Nobody should ever forget that this ENTIRE thread is about peoples OPINIONS. I'm seeing lots and lots of people saying "OMG this game was first!!!", or "This game was the most popular!", when that is not what this thread is about. The way we should go about this, is look at a game, determine it's key features, then look at the games released over the next few years. If a majority of those games have a majority of those same features (not just basic, feel free to nit-pick), then that original game can be considered to be influential. This is the most methodical way that I can think of right now (i'm tired). I'll stop here, and allow for responses before I continue.
