Sigma Star Force (atleast a remake to fix the old issues and revamp it)
Tube Slider /w online play :3 (it got bad ratings, but I loved that game)
Gotcha Force /w online play (the game was so fun with the anime look and all the toys you could collect. Kinda like Toy Commander but centerd on fighting along with collecting. Would be perfect for the DS)
Power Stone 1 and 2 (The DS needs its own version to over shadow te PSP port
)
Uplink (theres already a hacking game for te DS in japan, but something more like this PC game would be alot more fun. Its like a click and drag interface hacker simulator. Fun stuff)
Extreme G 3 (this game elped with speed withdrawls while I waited for Fzero GX)
Blaster Master (you know you want it)
Black and White (wasnt this game supposed to be out already? What happend to it?)
Toy Commander (with online play, just a crappy port would give more bag for one's buck)
Sega Rally (cuase I dont like the sony plastation wich has all the new Sega Rally games and the GBA port was way too blurry and limited)
Space Harrier
After Burner
Alex Kidd (Id love to see SEGA's old mascot make a return xD)
Doom (an origonal doom title, why not?)
Silent Hill (you know you want one)
Scorcher (I miss that saturn game)
Croc (it was a good 3D platformer, a new one would bring it back to life in a snap)
Lemmings (why hasnt anyone made this for the DS yet? Even a clone. Damn sony and their contract locking ways.)
Guardien Hereos (the origonal was the greastest brawling game ever)
Gunstar Hereos (the GBA game left me wanting more :/)
Panzeer Dragoon (it needs a portable version. Something better than that simple Gamegear one ofcourse, maybe a remake of that)
Final Fight triligoy (yes yes yes)
Streets of Rage trilogy (hell ya!)
Starfox 2 poert (Starfox DS is close, but I want the unreleased beta fixed up for the DS keeping the gameplay the same. So darn fan that one was
)
Road Rash origonal (the very first Road Rash was great with some nice looking graphics for the time)
Typing of the Dead (yes yes)
King of Fighters (since Capcom seems to be doing all its ports on the PSP, SNK should take their spot ;P)
Pokemon Cards (It was actually fun, I think they are making a DS version actually, I think Id like to try it out.)
Myst
D
and all other click adventures xD
Shadow the Hedghog xD (the game might be better if turned into half platformer half rail shooter xD)
