In my opinion i think its a stupid idea, RPG's and FPS's should be kept apart RPG's are most of the time boring lame and for young kids.  FPS's appeal to a larger amount of gamers like myself, therefore if the two were mixed, say if you mixed a RPG with say DOOM 3 were every head shot you get you recieve a gold coin,  then it would be stupid, who wants to get money for like killing someone????? its better if you just kill something or someone in a game and you get rewarded with new guns. not with money thats just ridiculous.
