There's also the problem that villains want to change the world into something bad, but heroes want to keep the world as it is - which makes the more static game world of an MMO way more suitable for heroes than villains - Paragon City is always being threatened by Villains, but it's still always there - so the default setting is that the Heroes have succeeded and the Villains have lost.
