Singapura already started a thread ( over here:
http://forum.arcadecontrols.com/index.php?topic=79831.0 ) asking what old games we have fond memories of. So, I want to turn that idea on its head. . .
What great old classic games have you only discovered recently -- through MAME or otherwise -- that you never saw or never got a chance to play Way Back When?
I was very much into space shooters, so. . . . .
Bosconian! I don't know why I never stumbled across a Bosconian machine in any of the arcades, I'm pretty sure it's not a really rare game. When I finally discovered this game, my feeling was: THIS is exactly the sort of thing I would have gone nuts over (and still is pretty fun today).
Zektor. . . More interesting than Space Fury -- and I liked Space Fury pretty well.
Major Havoc. I only heard about this game when people started calling on Jeff Minter to create Major Havoc 2000 (he never did). I didn't know what they were talking about.
Black Widow. Hmm, there were a lot of vector games that I never encountered. I wonder why?
ColecoVision games: I had Venture, Lady Bug, Carnival and Cosmic Avenger on my CV. I never saw a Lady Bug machine, and I only saw a Cosmic Avenger machine one time (and didn't get a chance to play it).
Blaster! I never heard of this game until Jeff Minter wrote on his website about it -- and his own surprise at discovering a forgotten Williams treasure.
Other Williams games. . . Bubbles. Never heard of it until it came out in the Williams games pack. I also recently stumbled across Mystic Marathon. I don't think either of these would have been favorites for me, if I'd seen them back in the 1980s, but I would have given them a spin. (Heck, I'd even play Dig Dug if nothing else was available. I drew the line at Mr. Do though.)
As I move forward into the late 80s and on into the 90s, the arcades were closing up around here and games were disappearing from convenience stores, and there are a lot of games that I basically know only from emulation, or from very brief encounters. There's Rastan and Rygar. . . (I know Rygar from the excellent Atari Lynx port.) Truxton and Vindicators were both games I loved at first sight, but only saw them one time, while traveling.
Nostalgia for old favorites is a fine thing, but it's also fascinating to dig through the whole history of video games and see all the stuff that I missed before.
