The Xbox 360 wired controller works pretty well for DCUO. I bought a controller for some of my GFWL games and found it to work well with Champions Online. For DCUO, you'll have to largely ignore the onscreen PS3 button prompts and do a bit of trial and error, but the gameplay works well.
Overall I like this game, but feel it's just missing something. I see no chance to knock down buildings, nor do I feel like I have to worry about property damage or that my actions matter. The game world would benefit from phasing so that my actions have results I can see. As it is, I complete my tasks and am told to move on while the chaos around me continues unchanged.
I like the fighting combos and counters. You can block, learn moves to overcome blocks, learn moves to counter attacks, and modify your travel powers into comic book movement based attacks. The game need another year or two of polish, but its fighting does feel nice.
