Arguably the best Xbox game ever, Knights of the Old Republic merged RPGs with Star Wars to create something special. The open gameplay, great story, amazing Jedi powers, and the fact you get to wield a lightsaber make KOTOR easy to love. Your actions towards good and evil also effected the storyline making multiple playthroughs a necessity.PGR2 improved on every aspect of the original PGR that launched alongside the Xbox in November 2001. Better graphics, smoother gameplay, more cars, more tracks, better soundtrack \u0096 PGR2 had it all.For a long time DOA3 was the only real fighter on the Xbox. And then Soul Calibur II came out and showed everyone what a real 3D fighter is supposed to be like. Soul Calibur II featured great gameplay along with a large cast of fighters (including Xbox exclusive Spawn).At the time it was released, Sands of Time was completely new and innovative. The graphics were gorgeous and the acrobatic, time altering, exploration heavy gameplay was a welcome change from the hack and slash bore-a-thons most action titles had become.<p>Crimson Skies made airplane combat fast, furious, and easy on the eyes. It is extremely easy to get into and dogfighting on Xbox Live is a blast.</p>Beyond Good &amp; Evil will probably go down as the most under appreciated game in history. After lackluster initial sales, Ubisoft slashed the price of the game in only a few short weeks. Thrifty gamers picked it up for cheap and it quickly became a cult classic. To the non-hardcore, however, BG&amp;E is still largely unknown which is a shame because this game is amazing.A personal favorite of mine, Operation Genesis gave you complete freedom to create your own Jurassic Park. It was a real time sim game where you built a park, cloned dinosaurs, and tried to attract visitors. The best part is that you could just sit back and watch your dinosaurs which is a real thrill. Or, you could knock down the fences and let your critters go wild on your visitors.Marvel vs. Capcom 2 still stands as one of the best 2D fighters ever. The gameplay is fast and frenetic and the graphics and animation are some of the best you\u0092ll find in a 2D fighter.Panzer Dragoon Orta is a gorgeous looking \u0093on rails\u0094 shooter that had you riding a dragon and blasting everything in the sky. It is known for its difficulty but it is also extremely satisfying when you see it through to the end. Well worth playing for any Xbox owner.Voodoo Vince is a 3D action/adventure/platform game that traded most of the platforming for some great puzzles. The main character is a voodoo doll so, as you can imagine, his best offense is to actually hurt himself in order to hurt others. This creates a lot of funny and cool situations that make the whole experience unique and really enjoyable.
