Gamertell offers its own preview look at the upcoming MMO, DC Universe Online, based on the playable demo at the 2009 San Diego Comic Con.
From the article:
"Like all MMO's you can team up with your friends online and complete quests, or just go all out and take out as many villains as you can. Sony is working on allowing the PC and PS3 to work together for online play, which would be nice for those who have friends that don't own one or the other. You acquire quests by either approaching super hero's and asking them if they need help, or sometimes they will call you up and ask for you help."
