I was once the opposite. I despised realistic games, and would play nothing more realistic than Rayman and Ratchet & Clank. From there I played LittleBigPlanet and wouldn't take a single step any further in that direction. But after that I played Resistance: Fall of Man, Resistance 2 and then inFamous. Yea from there onward I would play pretty much any game.
I recommend trying the Tearaway demo to see if you like it or not… infact I would suggest the Vita demo above the PS4 one. It's a good demo, and can really determine how much you may or may not like the game.
I myself am very on the edge about Tearaway. It seems to be a little too far on the kiddie side, but I can stand it for the awesome gameplay and graphics. I have been known to turn down games for being too childish though… looking at you LBP PSP!
