I got 2600 points in ny account and want some input on what to spend it on

Hi everyone. I am undecided right now. I got my eyes on several games, the main candidates are:

Arkham City (I loved the first game)

SSX (the demo was amazing and I loved the predecessors)

Tales of Vesperia (because I have a serious lack of JRPGs in my xbox collection)

Deus Ex HR (heard great things about it but only played it for 5 minutes at a store)

AC Brotherhood+Assault on Dark Athena (cause they are only 1280 points each and I could get two games I am interested in)

Any input would be greatly appreciated, I like to know which of these will give me the biggest bang for my buck. I am also open for different suggestions and generally like RPGs, Strategy games, action adventures and puzzle games.
