(I suppose this thread could go in either the Classic or Modern gaming forums, but since the end result is about discovering classic gaming experiences I chose to do it in the Classic forum. Please move if deemed appropriate)
So I just finished the Murderworld level of Marvel Ultimate Alliance. Part of this level involves your characters entering and playing full-fledged versions of both Pitfall and Breakout, complete with old-school graphics. Making my buddy Iron Man hop over rolling logs or swing on a vine over the quicksand brings me one step closer the Having Seen It All in this life.
But it got me to wondering what other newer games out there contain classic games inside? I'm not necessarily talking about something you unlock or some sort of background cameo. I'm more interested in finding out what, if any, modern games integrate classic games as part of the experience, utilizing at least some playable functionality?
Along with Ultimate Alliance, the only other one that I know of is Shenmue, where Ryu can enter into an arcade and play fully operational games like OutRun. Any others like this?
