Sly Collection. Its the only PS3 game I'd give an 8.5/10 this year and yeah I have played all the titles mentioned in the thread so far. I actually enjoyed all of them even if some of them disappointed me they were still fun, I am just harsh at ranking and difficult to please after a certain level haha.
Sly Collection because I haven't played the sly games before and found them to be amazing platformers with a coherent story and entertaining dialogue. But the twist is there's three of them, not just 1, three games and the Move mini games are pretty well done too. How could this not be my PS3 game of the year.
