It's a really great game, however I'm not sure it's really worth getting into anymore if you missed the boat. If you think you'll enjoy it with just the base Rise of The Valkyrie set and no expansions I'd recommend it as that's really the only thing you can usually find for a semi descent price. However buying any of the expansion squads and heroes is ridiculous and getting worse with each passing day.
However, if you're rich... :shake:
