The game has a few bugs which are getting fixed. The downloadable content set up is a bit of a pain. The graphics are average to good quality. You are forced down allot of set paths. Some classes have better survivability than others. Managing 4 characters at once can be a bit slow (pause to set an action for each character) and hectic (10 characters all hacking at each other with spells going off) at the same time. The setting and story is a bit cliche lotr. Some classes have better skills to survive and kill than others.
This is one of the best games I have played in years. You have a massive story about saving the world. You have tactical blood spattered fights. You have a well thought out set of game rules to master. This is not a big graphics twitch action extravaganza. There's a little Chess, World of Warcraft, Lord Of The Rings, Neverwinter Nights, Baldurs Gate, Mass Effect and Knights Of The Old Republic mixed into one.
I'd say you are looking at 65 hours to complete. Less if you skip side quests. More if you want to find everything. Then there are replays so you can master dual wielding warriors, arcane mages, or backstabbing rogues.
Shame you cannot control a party online with your friends.
