How good is character customisation? Scope for unusual power sets? Don't really care about endgame content (or any game content, for that matter, I just want to make a hero and run (or preferably fly) around the city with them, then start again with a new character idea)
City of Heroes and Champions should be great for messing around with odd heroes, but both are utterly crippled unless you subscribe. Which is not a good way to lure me into becoming a paying customer but hey, their loss.
