I've had PAX on the brain today, and that's in August, which made me mess up the date for Sakuracon, which is later this week, in April. April.
Also, I neglected to mention the one thing I do know about City of Heroes - it has a system whereby a higher level character can take you on as a Sidekick, temporarily boosting your level and letting you rock the house while you're partied together. That seemed like an interesting approach to the level disparities that often arise in games of this type.
