I have an ACDC Premium and an XMen LE love them both! With the prices I have seen recently I would not buy either NIB again, but I would certainly buy both again in a heartbeat!
ACDC probably gets more play in my collection than any of the others. XMen a close second. For what its worth I have to work to get great scores on either of them, however, for those comparing this to that and that to this.... I have played Stern ST maybe 5 times. On the fifth time I made it to Kobayashi Maru. Not saying I could do it every time but just saying there is something that makes it markedly different than ACDC, so don't worry about the comparisons. Spiderman kicks my butt too, I can see the comparison to ST visually, but for some reason Spiderman is harder for me to succeed at... play it... if it still feels too similar.. then move on. I have heard Tron and XMen are mirror images, both Borg, but they don't play like they are mirror images.
