Daystar, stop making threads about games and get back to making threads about awesome British food! We need a thread about Lea & Perrins, dammit! Unless you did that one already, in which case, get on and make one about...I dunno...Seriously Strong Cheddar, or something.
OT: I often find myself self-inserting (you're right, that does sound dirty), even in games that don't call for it. Games like Mass Effect, Skyrim and Half-Life 2 are prime candidates for this, but I also find myself doing it in games like Gears of War on occasion.
In fact, pretty much every game I self-insert, even if it's just for a moment to taunt the enemy (whoever they may be).
