I honestly liked MUA: 1 more than 2, since I really liked the storyline there better with Dr. Doom & him stealing Odin's power. Reminds me of Loki! Anyways, usually I'd use characters liiiike Spiderwoman, Deadpool, Wolvarine, Ms. Marvel, Storm.. etc, etc; the ones that I'm more comfortable with. oo;
That reminds me - I really don't like the Underworld level in the first game, because you'd had to choose between saving Jean Grey and Nightwalker, and either wy, you'd get a bad situation for both of them??? Ugh, there was no way around that, and it sucked, imo. But all in all, I had good times with these games~ Parts of them were challenging!
