Probably not, just my nitpickiness rearing its head. I'm still in @Arkandel's camp on this one, though. Not that I'm going to log into someone's game that using an obscure ruleset *to bitch at them, mind... but I still think he's got a valid point. As many of us find ourselves with less and less free time, how many really want to use that slowly closing window to have to learn a whole new ruleset just to play on a new game? I'm pretty sure that's a factor in why so many people are looking to convert popular video games into popular RPG rules. Less of a learning curve, you already know at least the basics, now you just have to apply them to a new game and new terms.
