OK, some highlights I've picked out of the thread here that I have to say I agree with:
Zone of the Enders (and extended edition showing both parts would be great....just stop the kid from being so whiney!)
Devil May Cry series
Spyro the Dragon (original trilogy)
Ratchet and Clank
Jak and Daxter
Jet Set Radio
Star Wars: X-wing/Tie Fighter (actually, I think the X-wing vs Tie Fighter game would be the best one for this)
Crash Team Racing (a bit pointless given that Mariokart is still going strong and kicking ar$3. still, this was a great take on the genre and would be welcome)
Ico
Shadow of the Colossus
Legend of Zelda: Ocarina of Time
Legend of Zelda: Majora's Mask
TimeSplitters 3
Red Faction (GeoMod FTW! Imagine having a remade Red Faction on the Frostbite engine though?)
Baldurs Gate
(although I HATE them) Fallout 1 & 2
Uridium
Ape Escape
uLTIMA uNDERWORLD (Legendary suggestion. +1 Internetz win 4 u)
and lots lots lots more!
Really silly ideas here include:
Halo: Combat Evolved (really? What, were Halo 3, ODST, Reach and the XBLA versions of Halo and Halo 2 not enough?!)
Perfect Dark (already been done. Check out Perfect Dark: Zero or the XBLA version of Perfect Dark)
sonic Adventure (see above)
Pokemon (you do realise the style of these games don't you? they'd gain NOTHING from a HD remake)
Pong HD (you, sir, have a twisted sense of humour. This is a gloriously silly suggestion and I love you for it

)
Keep them coming - I'm loving some of these suggestions
