Skyrim. fantasy game. amazing main story line, 273 side quests that are just as fun as the main story line. it's a must have game. my favourite game of all time:) and i've been playing games all my life.
crysis 2. fps game. wonderful story and awesome multiplayer that is very unique and different from other games.
crysis 3. fps game. haven't played through the story but i'm sure it's awesome too. more updated version of crysis 2 multiplayer. intense graphics. ps3 and xbox isn't able to handle it on full and you need a very powerful computer/laptop to play it.
gta 4. third person shooter game/mafia game. number 5 is coming out in november or october i think?
dead or alive 5. Japanese themed combat game. i haven't actually tried it but it seems pretty good. and number 3 and 4 was really good so i'm sure number 5 will be just as good, if not better.
I'm mostly a computer gamer so i don't have that many games for xbox/ps3
