Like Diablo had, every other game in the FPS/RPG/MMO genre should have...Ironman servers. Obviously you'd have to tweak the rulesets for each genre - like no regen health in FPS' - but the principle is sound. Those who want a real challenge, go Ironman. I haven't done that in Fallout NV yet but I'm damn sure going to. And I hope they have Ironman servers again for Diablo 3. I'd love to see every MMO have an alternate ruleset server with some kind of Ironman mode - maybe like 3 strikes and yer out type thing for permadeath.
