And I'm not even that old.
I recently found my old Game Boy and even I was surprised by how hard the games were compared to modern ones - it had been some time! I remember Duck Tales as having been great fun, but I couldn't even finish one level after over 10 years away from it! Ditto Gremlins 2.
I also remember being accused of heresy by an older school Atari gamer when I said that 'Defender Of The Crown' was crap.
My earliest memories of gaming were on a Commodore 64, playing classic stuff like Jet Set Willy and Mask (also a popular cartoon and series of toys in the 80s, sadly hasn't seen a revival to my knowledge but I'll be looking it up), then a Vic 20 after the C64 broke. Tape based games and old school programing with lots of 'goto' lines. Eventually we (me, my brother and sister) got a Nintendo (NES) with Super Mario Bros. and Duck Hunt. I clearly remember watching a film called 'The Wizard' about some video game tournament which was basically a long (and effective on my young self) advert for Mario 3, and of course getting the warp whistle in the manner shown in the film. I can't really remember many other games we had for the NES other than Defender of the Crown, Snake Rattle & Roll (which was immense) and Donkey Kong, I think we borrowed Mario 2 and Micro Machines which were both rather good.
At some point we acquired a Master System circuit board (no casing) but I don't recall playing much other than Alex Kidd which was built in. By this time I think we has received a Super Nintendo for Christmas, bringing the awesomeness of Super Mario World (we has 92 levels before we lent it to someone who saved over it!), F-Zero, Mario Kart, Zelda, Starwing, and most of Nintendo's output at the time, and some obscure classics like Pop & Twinbee, Mystical Ninja (STICKY NINJA!), Top Gear (nothing to do with Clarkson) and Muscle Bomber, possibly the best wrestling game ever committed to cartridge. I wasted many hours on Wing Commander and Sim City, and had many 4 player sessions on Super Bomberman.
One Bonfire Night we got a Megadrive, which led to us getting the first decent console football game (the first Fifa) and later spending many Saturday mornings repeatedly finishing Sonic 3.
N64 brought the joys of a 3D Mario and Zelda (two of the best games ever made) and the icon that is Goldeneye, (possible the best film tie-in game ever made). Oh and Mario Kart 64, a game I played almost every day for about 2 years. I loved the N64 but the sudden availability of cheap pirated games for the Playstation meant I was spending more and more time on Sony's grey demon. Worth it for Final Fantasy VII of course. I cried when Aeris died. You did too. Admit it. FF8 was good but pales in comparison. I've still got the memory card somewhere. Also during this era we got a PC and I played the likes of Command and Conquer and the last FPS I gave a shit about, Quake, with it's multitude of crazy mods (moshpit mode anyone?).
Then I went to uni. About the only games I played during this times were various versions of ISS/Pro Evo and Grand Theft Auto, and Final Fantasy 10, which has that irritating underwater volleyball thing going on.
From what I gather I didn't miss that much. Gaming made no great leaps during this era IMHO.
I had a brief time with a GameCube late into it's life and learnt to hate Super Mario Sunshine. The flawed version of Mario Kart helped coax me back into proper gaming though.
I bought a DS sometime in 2005 before any decent games came out for it, but after New Super Mario Brothers my collection has increased somewhat. Then we (this 'we' being me and future wife) got a Wii on the day it game out. A such I'm back into gaming properly on these two systems.
I lost the thread of what I was on about. Must be my age.
