Highly recommend Splinter Cell Chaos Theory if you're a fan of the stealth genre

Jade Empire

Breakdown might be worth a look for the combat and storyline, I've wanted to check it out myself for a while now

gonna have to pass on the splinter cell one for now as i’m not into stealth games sadly

Tragic 😔

Try looking into Crimson Skies High Road To Revenge then, and I hear FromSoft's Otogi games are cool

Conker Live & Reloaded if you've already played the original and want to play it with a new coat of paint and compare it to its original counterpart. It's not the best remake but its worth playing at least once.

Crazy Taxi 3

I love Fable Lost Chapters, all time comfort rpg.
Grabbed by the Ghoulies is neat combination of Combat/challenge rooms with a fun "spooky!" setting.
Nightmare Before Christmas is a cool DMC clone (Made by Capcom!) definitely recommend if you like the Movie at all.
Oddworld: Munch's Oddysee is kind of a hard reccommend cause *I* don't even like playing it tbh, but it SCREAMS Xbox to me.
Zapper: One Wicked Cricket! if you like Frogger gameplay.

Funny: Kung Fu Chaos, Raze's Hell
Real: Phantom Crash, Outrun 2

Spikeout: Battle Street and Dinosaur Hunting. I personally haven't played these yet, but they look pretty neat.

Pac-Man World 3 because it is such a genuinely fascinating game compared to the first two.

MechAssault

Conker: Live and Reloaded is essential. Better than the original N64 one, and with the added second stick, actually a pretty good early third person shooter.
