I have said before when discussing City of Heroes that it was not a game that really supported alts terribly well. There are a lot of other games (such as World of Warcraft and Star Wars: The Old Republic) that do a better job of ensuring that your alts get benefits from your main character. But CoH did give you lots of space for alts, and perhaps most importantly, it made sure you absolutely always had something to do with your alts. This was a wonderful and dangerous thing.
The reality is that if I can conceivably have alts in a game, I will have alts. And if I can’t conceivably have alts (such as in Final Fantasy XIV) I will still have alts. My character slots are usually full to bursting. I don’t care whether or not they’re necessary, you can make me get through a grindingly slow storyline multiple times and I will still do it. I need my alts.
But there are people who have two or three characters at most, and others who I’m told have just one character and that’s it. So tell us, readers: How many alts do you usually have in an MMO?
