I bought a bunch of games on black friday and I have  ahard time deciding on what game to play first. This is a reason why i dont like buying multiple games at one but they were all good deals.

Games-

Demons souls

Killzone 2

Batman AA

3d dot game heroes

NBA 2k11 (but ill be playing this along with other games).

Another copy of uncharted 2
