I remember playing as Emma in X-Men Legends. I liked all of her powers except Fear. There is NO POINT in making all nearby enemies run away. It only makes it harder to gain experience points.
I also kinda miss how unbelievably broken Jean was in the first X-Men Legends. Walk into a room, use TK, and EVERYONE in front of you gets slammed with both psychic and physical damage. There were rooms that got cleared out immediately. But they (understandably) had to nerf her in XML2 so that her TK only hit one person at a time.
Dr. Strange and Invisible Woman's powers make for poor substitutes, with their single-damage type attacks.
