I never had a Sega Master System - which I think was the first really cool console - but I did play my friend's one a lot. There were some good games that I have fond memories of.
But then the Sega Mega Drive (a.k.a. Sega Genesis) which was the finest gaming console for its time ever, as far as I am concerned. The Super NES ranted and raved about its wonderful 32,000 colours, but the Mega Drive had a CPU that was twice as fast, and with its 256 colours still looked better because of the more mature, sophisticated graphics. 32,000 colours is fine, but when you play a game like Mario with only a dozen cartoon colours, you're missing out on the extra grunt that the Mega Drive had.
And I still load up my Mega Drive to this day....
The games I still play are:
The Chaos Engine, Biohazard Battle, Streets of Rage, Streets of Rage 2, Street Fighter Special Edition (which apart from the poor sound quality is an arcade-perfect version of Street Fighter Championship Edition/Street Fighter Hyper Fight).
The games I don't play much but still like are:
Eternal Champions Chakan Alisia Dragoon
The games that I don't play any more are: Mortal Kombat Space Harrier 2 Altered Beast Clay Fighters Columns Super Monaco Grand Prix 2 Rambo 3
The games I fondly remember playing but don't own (and maybe would not enjoy anymore) are:
Road Rash 1/2/3 Megalomania General Chaos Rolling Thunder 2 Raiden Trad Batman Battletoads Super Off-Road Shining Force 2 Mortal Kombat 2 Ramparts Thunder Force 1/2/3/4 Wonder Boy 2 in Monster Land (not 100% sure of the name because there are two versions with nearly the same name) Wonder Boy 3: The Dragon's something (the one in which you became Mouse-Man, Piranha-Man, etc) Dragon's Trap (I think that's the name - it was a pinball game with a heap of extra stuff).
Well, that's my list for now. I'm sure I'll think of more later. I love my Mega Drive, which was built to last. The number of times my cartridges have flown through the air, hit a wall and landed with a thud (I get really angry at some of those old games) and never had a problem is just amazing. And I have a second unit that I found in a bin that had been in the rain and weather for about a week; it works fine.
Anyhoo, those are my fond memories (some very recent) of my old-school computer game playing.
Of course before the Mega Drive was my old XT computer, on which more than a few hours of my life were sucked away by Moonbugs, then Hero's Quest, then all the SSR Dungeons and Dragons games (Pools of Radiance, Curse of the Azure Bonds, Champions of Krynn, and to a lesser extent Hillsfar).
Yeah that game definately sold a bajillion systems (TMNT).....I remember while it didn't have all the frames of animation that the Arcade Game did, the arcade game still looked better, the SNES had that mode-7 "throw the enemy into the screen" move that looked sooo cool.
Mario and Sonic games were the first console games I ever played, and still remain my favorite games today (SMB 1-3 and Super Mario World, Sonic 1-3). Hell, earlier just today I was playing Sonic 3 (as Tails).
Other games that have remained favorites throughout the years include Duckhunt, Tetris, Metroid, Shinobi, Afterburner, Pacman, the first Mega Man, and others that I can't think of right now.
