Old games you used to love but have not aged well

[EEPiccolo]

So I broke out my N64 over the weekend to test my N64 controllers (long story).  Anyway, I popped in Goldeneye 007, and boy was I shocked.  I remember absolutely loving this game before, but I could not play it now.  And if it was only the fact that the graphics are so choppy (really choppy) I think it'd be OK.  However, the headbobbing was awful!  Both my wife and I were getting motion-sickness watching it, which never happened before, and we used to constantly have deathmatches.  I've never gotten motion-sickness from playing an FPS until now.  Maybe I'm just getting old, I dunno.

Does anyone else have interesting experiences to share about old games that have not aged well for you?
