Marvel Ultimate Alliance: Gold Edition has 8 new playable characters. Dr. Doom, Sabretooth, Magneto, Venom, Hulk, Hawkeye, Cyclops, and Nightcrawler. I marked out after seeing the cover and picked it up yesterday without realizing that after playing it that is was the same game with downloadable content already on it.
So I spent $50 (in store credit) on something you could download for free on Xbox Live, I just haven't played MUA since December so I didn't know. The only thing that sucks is that if you plan on continuing a saved game, the new characters are at level 1 so they get killed pretty easy. Which I guess is good after all since I always complained it was too easy.
Sorry if this is old news.
