Oh good grief. I hope the old arcade counts, as nostalgic for me would be the Atari 2600 and that would have to be Pike's Peak, god that game was tough as nails.
Gauntlet, the original.
Sinistar (not a GOOD memory, either. Gods that machine was annoying as hell)
Star Wars, the Vector graphics version.
Let's see, other nostalgia...
Master of monsters on the Genesis.
Zillion, same platform.
Plane (play it on the 8088 cpu, otherwise you will insta-crash)
Liesure Suit Larry and King's Quest and Space quest... Actually, the one thing I will always remember from Space Quest is that blasted Slot machine (SQ II I think)
Yeah, alright, I'm gonna go meander around old thoughts for a while now...
