I was just about to start the same sort of post here but then I saw this one so I may as well add it in the way I was going to start the topic, mainly as I cant be arsed to retype the whole thing again ...........
I have been looking a the stuff coming out for the DS and have been wondering about games that have come before that would be good to see either ported to the DS or a new version to suit the handheld, not as a homebrew project but as a full commercial release. My main interests for these types of games were from the N64 and DOS era as they would be easier to port to the DS given the limitations of the machine. I know there are possible copyright issues or that the rights are owned by companies with possible no interest in the DS, but this is a wish list or at most a "wouldn't it be cool" list. Games like Mario Cart DS, Final Fantasy and Metriod have proven there is sufficient oomph in the DS to produce a decent looking 3D game given the right talent. Older games handled right can be an excellent source of material for an updated game, but alas in a lot of cases the developers miss that certain spark that made the game the triumph it was when it first hit the shelves. Anyway here is my list, its in no way complete, but I thought I would start the ball rolling....
Smash Brothers - Even a version based on the N64 version and then expanded with stuff from the later relaeses version with online matches would be real really nice.
FZero - This to would be a cool game to have with online play. I wasn't a big fan of the GBA versions but the GC and N64 ones were nice.
Dungeon Keeper - The game was excellent and could include online matchups
Magic Carpet - If Dungeon Keeper could be done the Magic Carpet would be easy as they both used the same engine (ish), again well suited to online play
Diablo - Didn't like the second version but an new and expanded version based on the first version would be awesome
A Bitmap Brothers compilation - Cadaver, Speedball, Xenon 2, Gods, Chaos Engine.....
Warcraft I & II - The original games brought up to date, possible online matches
Grim Fandango - An expanded version would be so nice
Little Big Adventure - The first one was a really nice game and would be well suited to the handheld
Pacman CE - The Xbox live was a pleasant surprise of a game.
Assault Heroes - Another Xbox live classic
Every Extended Extra - I have a homebrew version of this on the DS but an official port would be much better.
UNO - Carbonated games version on Xbox live just blows away every other version of the game I have seen, nice with online play and voice chat.
Cannon Fodder - Look what they managed to do on the plain old gameboy colour. Would rock on the DS "I kill you easy"
1080 Snowboarding - A mix of the N64 and GC version
Excitebike - A truly underrated game on the N64, screaming out for a remake on the DS
Mario Golf / Tennis - Not the RPG(ish) versions of the GBA but just the golf and tennis games that were so good on the N64
Blast Corps - A really unique game on the N64 that really fell under the radar, which was a shame as it was a really good game
Wave Racer - Another Nintendo Classic.
I cant really see why any of these would not possible on a technical level, anyway I can but wish....
