Here are some helpful topics-
Skill Books/Stat Books/Dragon Skill Books Complete - you generally do not want to miss skill points.
Character Optimization - this topic helped me very much. I never knew putting points in Intelligence could make me a very good Warrior or Ranger. Check this one out.
Help build char - same thing as Character Optimization topic. I was explaining some beginner's stuff to a new player.
I have played both Oblivion and Fallout 3. Though it is a good game, I have a certain disliking for Oblivion because of the leveling system. In that aspect, Divinity 2 offers immense flexibility, and replay-bility.
I hope this helped. Feel free to ask if you need anything more.
