Should you get Halo 3 odst or assassins creed 2?

it really depends on your video game preferencel. If you enjoy free-running games that you can enjoy by yourself, go for Assassin's Creed. But, if you perfer many types of multiplayer, amazing customability, and the best machinima-making game out for consuls, go for Halo 3. It is just my preference, but I like halo 3 more.
