I personally only own a PC an X-box, and a PS2 by proxy, and my tastes lean toward FPSs, RPGs, and MMOGs, I'll be relying on you the readers to assist me in keeping these lists up to date expecially for the GC, PS2, and Sports/RTS genres.
I want to get away from the Gamespot/Gamespy/IGN fluff and talk about games that matter, not just companies that feed review sites press kits and cash to hype up their crappy BS games (Hi Matrix Reloaded!). Here we'll focus on the games coming out that really matter. All of the rankings in the lists will be completely subjective, and can be modified if people think there's a need for it. Feel free to suggest any game, or change in ranking as you see fit. I'll try to make all of the game titles eventually links to the game sites this post will be forever a work in progress.
Without further ado, the games:
PC:
1. World of Warcraft - Blizzard Entertainment - MMOG - 6/15/2004
Arguably the most talked about, anticipated game currently in developement.
2. Half Life 2 - Valve - FPS - 6/2004
Can this sequel to the genre inspiring original, live up to the hype? Will it EVER actually be released?
3. Unreal Tournament 2k4 - FPS that has 10 different multiplayer options. Demo is the win so it will be hard for the release to disappoint.
4. Doom 3 - ID Software - FPS - 3/15/2004
Another eagerly awaited FPS sequel.
5. Battlefield Vietnam - Drop your BAR and pick up your M16 and go kill charlie instead of jerry.
6. Everquest II - Sony Online Entertainement - MMOG - 11/18/2003
Follow up to the most successful MMOG of all time.
7. Sims 2 - Maxim Softare - Strategy - 2/15/2004
For the people who wanted it, now with offspring!
X-box:
1. Halo 2 - Bungee Software - FPS - 3/1/2004
Arguably, there wouldn't be X-box sales without Halo.
2. Ninja Gaiden - Team Ninja - Action - 11/19/2003
For those that saw the trailer in Dead of Alive:Xtreme Beach Volleyball, this game looks awesome.

3. Starcraft: Ghost - Blizzard - Action - 02/11/2004
Looks to be similar to Splinter Cell in the Starcraft universe.
PS2:
1. Final Fantasy XI - Squaresoft - RPG - Q1 2004
The ever popular Final Fantasy line continues.
2. Xenosaga 2 : Jenseits von Gut und Boese - Monolith Soft - RPG - TBA
3. Grand Theft Auto 5 - Rockstar - Adventure - 10/15/2004
Hopefully more offensive than the previous 4!
4. Gran Turismo 4 - SCEA - Driving - Q3 2004
The best and most realistic driving game returns.
Gamecube:
1. Metal Gear Solid: The Twin Snakes - Konami - Action - 03/09/2004
Gamecube takes a swing at a sequel that hopes to be better than the first.
2. Resident Evil 4 - Capcom - Adventure - 2004
Find yet some more zombies to kill in the game that is the only reason some people buy a Gamecube.
3. Metroid Prime 2 - Nintendo - Strategey - TBA
Sequel to the massively popular Metroid series.
