Little big planet games are fun.
heavy rain is an absolute must play but I wouldn't buy it unless you are someone that likes to complete 100% because that would take awhile. The game does start of really slow but if you give an honest 2 hours I would bet you are hooked. There is no game out that is like it at all and I wouldn't read about the story at all. Honestly I never thought a game that you can't lose at would be as good as it is.

They have a similar graphical style. The areas are kinda small and linear but they make up for it by making everything really detailed. It is a very good game.
EDIT: Silly me I missed a major one. If you not played ICO or Shadows of the Colossus before get the ps3 collection. I don't think you could spend $40 on a better game or two.
