I know this can be quite subjective, but using these attributes, who do you think generally has the *BEST* 1st party library. And name 3 games to support your choice...
1. Diversity
2.Quality (reviews, goty, metacritic)
3.Technicality (graphics, controls etc)
4.Sales (avg and overall)
5.Quantity (amount of 1st party games released)
6.Amount of shitty games/shovelware
Ok, since I only own a 360, and the ps3 1st party library is similar to the 360 library...I would vote ps3 for diversity, quality, technicality, and having the least amount of shovelware.
1.UC2
2.GOW3
3.GT5
