I love MMOs, and I love comics, but this game... it had such potential. With a stable like DC and the Justice League behind it, this should have been the end-all of comic MMOs. But, sadly, the super-ball was dropped.
Setup is easy, character creation is easy- about the only difficult thing is leaving the game to patch overnight and then trying to find a character name that isn't sitting unused on someone's account. That, however, is where the feeling of making your own hero ends.
The story starts up- Lex Luthor has come from the future, spinning a tale of a universe subjugated by Brainiac, and he's brought gifts for everyone- exobytes that end up infecting hundreds of thousands of people with superpowers (the PCs). The Justice League is asked to train the heroes, and the Legion of Evil is tapped to train new supervillains.
What that essentially means is you get tagged to handle everything that they feel is beneath them- you never really get to feel like a hero or villain- instead of Batman, you'll get to be one of the Robins, but in a different costume. You get told to go here and help someone- it just doesn't feel like you get to be the hero or the villain- instead, you're a piece on a board that both sides are playing off against each other. Think of it like three-sided chess- the heroes and villains battle each other, but both know that if Brainiac wins, everyone's out of luck.
Honestly, there's a solid game in here, but the presentation needs a lot of work- if I want to be a hero, I don't want to be treated like the sidekick- I want to get out there and save the day from villains, not clean up their mooks and wait for some other hero or villain to swoop in and finish the job.
If the DC thing is important, grab this. If not, grab Champions Online. Simple as that.
