I don't think anyone wants to be a
hardcore player.
A lot of whining for hardcore MMORPGs is just whining for massive time sinks everywhere, rather than any increase in difficulty. And I get that some people want to feel special for wasting more time on a game than others, but you get a much larger audience catering to all the people with an actual life. I mean, it doesn't make for the most interesting kind of game, but a lot of the time sinks people lust after aren't actually that much more interesting either, they just have the psychological effect of feeling more rewarding to those with the time to waste on them. If you don't have the time to waste on massive time sinks, it's a complete turn off
I do want to see more MMO sandbox games, but a good sandbox MMO is all players and action. There's no place for a plot and scripted quests, it's all players shaping the environment and forming their own legacy
