I am playing DCUO at the moment, I am liking it. It's nice to fly around, kick the snot out of people, boot a fire ball at them and make my guy look like he is wearing deadric armour from oblivion.
I do have a few issues with it though, such as the vendors sell nothing for mid level people, except a drink (restores health and power), it goes level 3 stuff (which is what you leave the training area at) then jumps to level 19 for a drink then jumps again to level 24, then 26, then level cap 30.
The main areas for the heroes and villains sells nothing but level 30 stuff so there pretty much useless till then.
You can't interrupt a person speaking with you through the communicator or you will will have to listen to it again.
The music in the night clubs is 3 seconds worth of song on a loop, it drives you mental!
It is hard as hell I am level 21 and sometimes struggle to do quests 5 levels below me, I am stuck at the moment with 4 quests all the same level as me.
It's next to impossible to escape, as soon as you are hit you slow way down and the enemies can "ground" you meaning you can't sprint/fly/acrobat away, just walk which means you die, alot.
Lastly, booster fuckin' gold! These little machines tell you to take a tour of an area and this booster gold voices it and gives the history. The problem is his voice is so smug and obnoxious and he always says his name in the voice over, "I, Booster gold, will somebody have a statue next to superman's", granted they are newb quests to get a little EXP and a weak item.
