It's me! Hurrah!
Ooh, OK, I'll give this ago. Try and remember all the consoles I've had and the games on them...
Spectrum: O, Mummy!
Sega Mega Drive: Hmm, I'd day Golden Axe -- oh, heh, just saw that you've said the same, Remedy. I was torn between that and Streetfighter, but the ability to ride firebreathing dragons swung it.
Game Boy: Pokemon Red
Game Boy Advance: Pokemon Crystal
Nintendo DS: Argh, this is a hard choice. I liked Pokemon Platinum, but then White had some awesome changes in scenery...but just because it was very different to the usual Pokemon plot, I'll say Pokemon Ranger: Shadows of Almia
Nintendo 64: ZELDA OCARINA OF TIME!!! Still my all time favourite game. I've completed it about 63 times and that's not even an exaggeration.
Xbox 360: Erk. Well I love my free-to-roam games, so I just love Skyrim and Minecraft. But then I do so love Halo: Reach...I think if I had to pick just one, it would be Skyrim.
Quick addition -- played on the Wii a few times (and have always coveted one) and my favourite game for that, without a doubt, is Super Smash Brothers.
Bit of an update to this.
Xbox One -- Dragon Age: Inquisition
Wii -- Zelda: Skyward Sword
PS4 -- Final Fantasy XIV
