This is a classic RPG that absolutely MUST be enjoyed by anyone that calls themself a fan of the genre.
The world was huge and interesting. It isn't as immersive or interactive as something like Elder Scrolls. What it does have is a classic turn-based party combat appeal that has all but disappeared now-a-days.
This game is the penultimate example of how to do an old school D&D based RPG, only because the sequel is better.
Don't stop until you've played the sequel and Throne of Baal.
