One of the best games I've ever played! Really challenging, and hard to get the hang of, but once you do, the combat becomes so satisfying and amazing. The combat is very strategic and requires you to think before you make a move, or position yourself properly before striking. The world is beautiful and full of awe-inspiring scenes; it's unique and dangerous. The main draw for this game, IMO, is the fact that the game absolutely does not hold the player's hand. There's no minimap, no quest log, nothing but the faint guidance of grace that guides you to your next objective. All the bosses are unique and fun to fight, and very few are easy if you're not overleveled. I won't give it five stars, though, because it still has some incredibly annoying glitches, specifically when facing certain NPC invaders. Also, the dogs and bats can burn in hell.
Also, servers crash a lot and you have to close your game to opt-out of being online. I have lost many a boss fight due to being disconnected midfight. Servers need a ton of work. Also, a pause option would be nice. I have to go do things a lot while I'm playing, and some boss fights can get really long, so committing to a long fight or dungeon can be really difficult sometimes.
