First game had loading issues but I found it fun.
The voice acting and writing was HILARIOUS.
Second game, you're batman (really, for the first two hours the main character pretends he's batman when he talks).
It's fun too. I enjoy later game when I was in gigantic paladin armor with a massive polearm. I disliked the lack of freedom of choice though. I had to peacefully resolve too many things instead of killing everyone and anyone I want.
But of course, I have a god complex in western RPGs, so maybe i'm a little biased.
Lots to do. Lots to see.
