Quoted from Chambahz:I'm not trying to be a jerk, but you can see for yourself...
ACDC's the bomb and far more popular than Xmen.
While there are 550 XMen LE's out there I think one of the Stern insiders here said there were 6,000 AC/DC's sold already, with more on the way. There will not any more XMen LE's or Premiums on the way. XMen now has solid code and is an awesome game. Mine won't be leaving for certain.
My suggestion to OP is keep the XMen; cool mode based game with great art, unique shot lay out, great call outs, great custom dots, and (in my subjective personal view) the coolest Marvel super hero theme there can ever be.
