AFAIK, PS is going to/already does use RPG rules for combat, not FPS or Action game rules. That is to say, your character swings, calculations are made, dice are rolled, damage is dealt.
I don\'t think using RPG rules is original or realistic, and taking this different approach to combat would certainly be a plus for PS in terms of standing out from the crowd. Right now it just seems to be conforming to boring standards (like implementing combat first, instead of implementing anything else, why combat...? Etc).
At first I read this and thought I didn\'t like the idea... but thinking about it, it would add a whole new level of gameplay, and create a highly interesting, involved, realistic, original combat system that NO other (MMO)RPG has.
