Hmm...
I know you had some of the Atari carts on the third Win 95 Activision pack. That's what I'd like to see on a volume 2 (in addition to all the stuff everyone else has mentioned.)
I was kind of dissapointed over the lack of high score saves, but it seems like everyone else is mentioning this as well. That, I'm sure, will be in Volume 2, right?
I still think, if done properly, an Intelivision pack could be good. I was pretty dissapointed by the first one, but perhaps the technology is better now and that could be done well this time.
And, as already mentioned, interviewers with the programmers. That's about the only reason I've held onto the INTV pack for PSX. The interviews were great!
Still, great work on this one. I think this is going to be the yardstick against which all future retro comps will be judged, and that's a good thing.
