The PlayStation 3 version of the game features a userbase that skews younger than its PC counterpart, and Liberty says that DCUO is the first MMO experience for many PS3 players. He also mentions that PC players appear to be more comfortable with traditional MMO gameplay like guilds, groups, and raids. In terms of the eternal controller vs. keyboard/mouse debate, Liberty says he prefers the former. That said, "the top three finishers in our first-ever DC Universe Online Legends PvP Tournament at SOE Live last year used the keyboard/mouse setup," he explained.
Finally, Liberty says he expects the recently announced PlayStation 4 to "be a great platform for MMOs."
