I'm in the middle of Yakuza 3 (ok it's not really a RPG but it's a interactive movie/third-person brawler with gaining experience points, leveling up of abilities, etc.) On Chapter 10 (yay almost there!). I like it but honestly I think a game like this shouldn't have this much dialogue, cutscenes and boring gameplay (doing a lot of walking around talking to NPCs, fetching for items, etc.) and should have more kicking ass. The story is pretty good but for a brawler there's not enough brawling in this game. It's good enough that I'll rent Yakuza 4 but I didn't like how there are long stretches of down time in between action. I'd rate Yakuza 3 thus far a "good". Though I think I rated Nier a "good" too so maybe I'd downgrade Nier to "above average" and bump Yakuza 3 to in between good and great.
I also rented Valkyria Chronicles. Going to start that after Yakuza 3.
