1. Ninja Gaiden
2. Beyond Good and Evil
4. Crimson Skies
5. Full Spectrum Warrior
I'd be cruising for cheap used titles; this holiday is gonna rape your wallet.
I'd give up the FSW and just rent it first. Try both the arcade and hidden army versions, and decide if you want to spend the time in that game.
Giving up a game and getting Live isn't a bad idea either; that gets you mechassault free and gives BIG legs to crimson skies.
Check out a used Dynasty Warriors 4 if you like beat-em up combat against hundreds of enemies... the game has legs even though the graphics are a bit dated (40+ characters with their own stories). Otogi is definately good and falls in the same vein; it has significantly better graphics although it doesn't have the heroin addictiveness that is injected into most KOEI games (DW4 included).
A fun quirky party game would go to Kung Fu Chaos; a wildly underrated game that is funny and challenging. It's got a platformer feel to it; even if it's very rigid in terms of exploration. The multiplayer (up to 4 people) is a blast, especially if you've unlocked all the levels.
I highly recommend Ninja Gaiden. If you *need* a platform game Vexx is alright; it has it's moments. Plus it's dirt cheap. There's a Sonic game if Rings is what you need.
Burnout3 isn't a racing game; it's a vehicle combat game like Carmageddon. Try it, buy it, enjoy.
Riddick is good, Halo is better.I found Riddick to have some good times, but it's over SO quickly.If you have any friends with Xbox, borrow their halo. Oh, and play co-op mode; it's the best there is.
As far as spiderman2 is concerned; the PC version was horrid. The console version is excellent. Once again, borrow from a friend, until you get tired of saving stupid roofworkers from falling.
