I wish they had star ratings on the eshop as they do on the PS store. OK so they're not the gospel according to the patron saint of gamers but they're a great guide.
It'd make the decision on buying those random indie titles much easier if I could see a consensus from the other players. I feel like I'm stuck buying the crappy ones and missing some quality game play. I do look into reviews but you have to take them with a grain of salt.
I don't pay any attention to the star ratings in the PSN store. I need to know why people like the game, not just that they like the game. There are some really popular games (especially on Nintendo) that I want nothing to do with. I read or watch some thorough reviews elsewhere to assist with purchasing decisions.
