The Playstation 2 was famous because it had an extensive library of Japanese and Western RPGs. Sadly the same can't be said for the Playstation 3, which has been on the market ever since November, 2006. After almost two years, the Playstation 3 has very little to offer the role playing enthusiasts.
Microsoft on the other hand seems to be the opposite. It appears that Microsoft is fighting tooth and nail to offer gamers a diverse selection of RPGs which vary in both western and eastern themes.
