Castlevania

If you own an Xbox, I would give serious consideration to Harmony of Despair. It's Castlevania's jump into multiplayer. I will admit, it does take some getting used to, but once you get going with some good equips, you won't want to stop. I put over 500 hours of gameplay into it, and I still wasn't bored. It's definitely different, as it doesn't follow a story. It's just 11 HUGE stages you can play with up to six people.

That's on the PSN as well, although I do not know if all the stages are supported. I know that HoD originally came with only 6, and that was something people complained about (and also the reason I didn't get it myself). I didn't know they added 5 more. I'll have to check it out myself. Thanks.
