Balance! Thats what D&D is all about. It's the most balanced core rules for gaming ever created. However, apparently Balder's Gate: Dark Alliance 2 likes to claim the D&D rules without actually using them.
This game is fun at times, and in 2 player mode is good to kick around with a friend, and certainly it has a D&D style storyline. But the game just simply isn't balanced. It's either way too easy, or far too difficult. 90% of the time it's too easy. Just for fun my friend and I made brand new level 1 chars and imported them into the Extreme mode. At first were were having our rears handed to us on a platter, but eventually we started kicking butt like normal, and this was with a rogue/monk combo!
If you play with a cleric/barbarian combo you might as well type "I win!" and be done with it.
