Simply addictive, just hard enough, challenging like the good old games.
It had been a while a game prevented me from sleep and nourishment that bad... I mean last hit I had was uncharted 2 but this game is something else.
Graphics are okay, music okay too, the gameplay, very very fun. The best part though is the challenge. The amount of time i died in the beggining was phenomenal. I haven't died like that since the SNES or maybe GoldenEye for the N64 on hardcore 007 settings...
You can die 20 times in a row but sometimes you just don't care. Sometimes you die once in a four hours strech and you want to litteraly kill someone... (good thing you can go player killing to relieve the pressure and to get back to life :)
Try it it's nice, the story is intriguing and the RPG aspect is always nice and finely tuned.
Have a go at it, and come back crying.... Well until you crawl back up from death and vanquish the Old One.
Have Fun
