Must have Xbox original games

[AnAngryMoose]

Timesplitters and Beyond Good and Evil.

My Xbox lineup I loved:

Halo 2 (I borrowed original from a friend so I had that too)
Kotor
JSRF
Star Wars: Clone Wars (not that great but fun if you like SW)
Kung Fu Chaos
Forza ms
Jurassic Park: Operation Genesis (epic game!!)
Fable
Star Wars: Jedi Acadamy
State of Emergancy
Star Wars: Trials of Obi-Wan (don't bother with this, it's ok but I like Jedi Power Battles more)

I had a bunch of demos too. Basically I'd recomend Kung Fu Chaos as a fun little game if you can find it cheap, JSRF because it's awesome and Jurassic Park (although you might be better off getting it on the PC). State of Emergancy is kind of like Dead Rising but without the zombies, which is cool.

The original Mercenaries. I know it wasn't an Xbox exclusive, but damned if it wasn't/isn't tons of fun.
Oh, and one more vote for Republic Commando. Most fun I've had with a Star Wars game without the words Old Republic in the title.

If you liked KotOR I, then get KotOR II as well. It's pretty glitchy when you play it on the 360, though. There's an audio glitch (a noise...like KRRRCHZST I experienced very regularly from beginning to end). But Obsidian added some very useful options to the abilities when you level (especially Finesse). They did omit some of those abilities from Blaster Rifles, though, so that method of combat is far less effective than all of the others.

Other than that: Beyond Good and Evil, Psychonauts, Jade Empire, Splinter cell: chaos Theory, Fable, and Star Wars: Battlefront 1 and 2 are all great.

Steel Battalion.

Kung Fu Chaos, anybody?

I have it. I use nothing but Bowling for Soup songs >>

OT: Star Wars Battlefront 1 and 2
TimeSplitters 2 and Future Perfect
Fable: The Lost Chapters

Kung Fu Chaos, anybody?

This is the first time I have heard of this game since I owned it many years ago... such a great game, and if you have anyone you could play it with I'd definitely say this.

Other than than that though: any Timesplitters game (though that kind of relies on multiplayer again), Morrowind if you can't play it on PC, Halo 1 and 2, Kotor 1 and 2, Star Wars Battlefront 1 and 2, Splinter Cell 1 2 and 3, Stubs the Zombie...

A lot of people may disagree on this one, but Deus Ex: Invisible Wars I found really fun, enough to complete more than once.

There's a bunch more too, but I unfortunately can't remember most of them...

Jade Empire is a great choice if you liked KotOR.

This. This was the only reason I had an Xbox.

 

[Dragonblade146]

Jurrasic Park Operation Genisis, The Punisher, and Halo.

 

[Jopoho]

Circus maximus if you can find a friend to play it with you. It's not "good," but it is still worth checking out if you can find it.

Indigo Prophecy

I've had that game for longer than I remember but have never played it, how long is it? If around the same length as Heavy Rain I might do a marathon with some friends.

Been a while since I played it, but I'd say around 8 to 10 hours for a play-through.

Most goodies have already been mentioned so I'll just fling my favorite in the mix:
Vince the Voodoo-Doll

 

[Monquart]

Most of the good one I like are already mentioned. Except for The Warriors nothing more gratifying than smashing someone against a wall or one of the flying tackles.

Since you have KotOR 1 I'd suggest
1. KotOR 2
2. Elder Scrolls 3: Morrowind
3. Indigo Prophecy
4. Fable The Lost Chapters
5. Jade Empire
6. Ninja Gaiden Black
7. Chronicles of Riddick: Escape From Butcher Bay
8. Psychonauts

You can also try Halo 1&2 if you're into shooters however I've never been able to get into Halo series and have never played them in-depth as much as I have the ones I listed above, however, Halo's success did cement the Xbox as a real contender in the console wars, so I guess it deserves mention.

 

[Biodeamon]

I'd name a few titles but Sony usually steals original titles eventually (Deadspace extraction for example. Rage.)
