I can't believe I almost missed out on this and ROF because of bad press. It's a good thing forums like this one exist.
Haven't finished my first playthrough yet but here are some thoughts:
More monsters would have been nice, the game needs more variety, you spend the whole game fighting pretty much the same monsters. Some of the boss fights are fucking epic though (like GoW epic).
Graphics won't blow your mind but do their job well.
Kaine's outfit is ridiculous, when my wife saw her on the screen she was like "WTF?"
It can't be said enough, the soundtracking is amazing, breathtaking, a masterpiece.
The characters are great and the story is very interesting, it slows down a bit somewhere between the 5-10 hour mark but bare with it, you wont regret it. You will witness some truly memorable and touching moments.
Weiss' VA did a brilliant job, one of the best VAs ever for me. VA overall is very good. Some lines are brilliant, pretty much every dialogue between weiss and kaine is hilarious.
Considering the game can be found cheap now (I got it for 19,5 euros) I honestly think that nobody will regret buying it. It's really good.
