Sinclair Spectrum 128k +2a
Roadblasters, Operation Wolf, Ghouls and Ghosts, Ghosts and Goblins, Green Beret, School Daze (I'm going to unfoundedly and outrageously claim this as a likely inspiration for Bully and even in it's own limited way the sandbox style of gameplay), Chase HQ, F40 Challenge, BMX Simulator (Think I read that this was the first one from Codemasters, wasn't especially fun, but this is kind of what games were like back in those days, and I played it a tonne).
Status: KIA

Sega Megadrive (japanese import)
Golden Axe, Strider, Ghosts and Goblins, Bare Knuckle / Streets of Rage, Pitfighter (even though it was clearly pants), Road Rash, John Madden, EA Hockey, Ok, I suppose Sonic the Hedgehog too. That Shinobi style thing where you wound up fighting the t-rex (or t-rex skeleton depending on the version you had) in the hull of a tanker - can't think of the name of it at the moment.
Status: Sold

Atari Lynx (I so blatantly should have resisted my inner graphics whore and got a gameboy)

Only ever had Shadow Warriors for this which I suppose makes that memorable even though it was SO hard. Lynx's novelty feature was that you could set it up left or right handed, so you basically flicked a switch and it flipped the video output so lefties could hold it upside down, must have seemed like a good idea at the time...

Status: Sold

SNES

Super Mario World, Legend of Zelda, Streetfighter II Turbo, Mortal Kombat, Actraiser (Populous meets Rygar just worked for me way more than it should have, it really wasn't that great at either bit), Super Mario Kart, Super Ghouls and Ghosts, there must have been more...
Status: Sold

Playstation
Soul Edge (or Blade, forget which was UK arcades and which was PS), Tekken 2, Final Fantasy VII, Gran Turismo, Gran Turismo 2, Final Fantasy VIII (although my overiding memory of this is that I copied my 25hrs in game save on to a new memory card off the front of a magazine, and deleted the original before trying the new one - oops. Never had the willpower to revisit it, which is a shame because the gunblade had that whole Ulysess 31 cool about it), Final Fantasy IX, Suikoden, Resident Evil, Resident Evil 2, Nemesis (which I loved but didn't play that mutch of), best for last Metal Gear Solid
Status: I think I actually gave this away

PII 266, Windows SP2 (now with usb support!)
Quake II, Half Life, Half Life Blue Shift, Half Life Opposing Force, MAME.

Playstation 2
Metal Gear Solid 2, Silent Hill 2, Resident Evil Code: Veronica, Medal of Honour, GTAIII, GTA San Andreas (is mainly missed Vice City, had actually only got around to III when it came out, which is definitely a shame), Gran Turismo 4.
Status: Sold

Nintento Gameboy Advance
(Worst handheld EVER no backlight? what were they thinking?) Genuinely struggling to think of anything I had for this, Bomberman, Yoshi's Island, I get the impression I had StreetFighter II for this, though I may just have made that up.

Nintendo Gameboy Advance SP
(fixed both of the problems with the original - backlight screen and a rechargable battery).
Advance Wars, Legend of Zelda: A Link to the Past

Game Cube (very briefly)
Legend of Zelda The Wind Talker, Resident Evil 4, Metal Gear Solid The Twin Snakes, Soul Calibur 3.
Status: Sold

Playstation 2 Slimline
Gran Turismo 4 again, Farhenheit (this game was amazing, why didn't I get around to finishing it?), Killzone (it's style more than how it played).
Status: Sold

PSP (japanese import - UK release delayed until well after my summer holiday? sod that my friend)
It's a sorry state of affairs that I had the most fun with this using a SNES emulator on the 1.5 firmware, that and the emulated Doom II (even though the controls were awful in that). Still the games landed evenutually: Metal Gear Solid: Portable Ops, Syphon Filter: Dark Mirror, Syphon Filter: Logans Shadow, TOCA Race Driver 2, Locoroco, Grand Theft Auto Liberty City Stories (this is when the PSP came good - a technical marvel), Tekken: Dark Ressurection (where the fresh hell is the PSP's Soul Calibur?), GTA: Vice City Stories, the ability to rip DVDs to watch on the commute to work.
Status: KIA

PS3
Uncharted: Drake's Fortune, Resistance Fall of Man, Call of Duty 4, GTA IV, GT5 Prologue, Metal Gear Solid 4 (and I haven't even started playing it yet, still... I've calmed down after the MGO beta fiasco, so that's progress of sorts, I basically want to start in to this when I have time to dig in for a session and am not too tired, no time at present for that), Rub 'a' Dub (my 5 year olf daughter loves it)

Status: Main console

PSP Slim + Lite
Final Fantasy Crisis Core, Pursuit Force, Harvey Birdman, Hot Shots Golf (it's gone all dry on the PSP horizon again hasn't it? Did I read rightly at the end of Crisis Core that the FF VII remake proper was in the pipeline?), Not being able to encode DVDs under Vista has stopped my bothering to buy DVDs and it is really dissapointing.
Status: on the back burner since I finished Crisis Core, but still in the bag for my daily commute.

Nintendo Wii
Wii Sports, Wii Fit
Status: my wife's first console - which is really the genius of the Wii.

Nintendo DS
Brain Training, Legend of Zelda The Phantom Hourglass, Professor Layton and the Curious Village (bring on the next two, I'm really enjoying this).

If anyone has actually skimmed this far I'll be amazed, started writing this for a bit of speccy nostalgia really.

toodle pip!
