What is the difference between

Silent Hill 2

Silent Hill 2: Director's Cut

Silent Hill 2: Restless Dreams

Thanks

I'm looking for a very long single player game with a good story that will last me a while

(I have already played BioShock and Oblivion)

How similar is Splinter Cell: Double Agent to Metal Gear Solid 4?

Does Halo 1 and 2 work perfectly on the Xbox 360? Also, how well does Conker: Live and Reloaded work on the 360?

Which of these games has the most replay value?

Mass Effect

Dead Rising

Perfect Dark Zero

Gears of War

The Orange Box

Left 4 Dead

(Note: I cannot connect to Xbox Live, so I cannot play online multiplayer)

Also, is Assassin's Creed worth buying or should I just borrow it from a friend?

Will Xbox 360 games purchased in the UK work on an Xbox 360 purchased in the US?

Can I download DLC on Xbox's site and then put it on a USB and then install it on my Xbox? Also, can I do the same thing with downloadable games?

I'm looking for a game that has competitive multiplayer similar to that of Star Wars Episode III the game

I'm looking for a 360 game where you can play multiplayer with a friend against other computer players (Similar to Quake III Arena)

Also, I own Oblivion for the PC, it runs a little slow, and I want to get it on the 360, should I get Oblivion or The Orange Box first?
