All they ever created was excellent and original. Starting from the gameplay to graphics and sounds. Yes, well, it is most action based. Each has his own weapons and magic spells. You will play game in 4 huge worlds, combined with big places called hubs.
Game is fun, addictive and hard.
Yes, very hard. Not so because of monsters, but adventure parts. Very stressfull really. But when you really get into it, all you have is hours and hours of fun. Game is powered by Quake engine, and in the time Quake II was comming.
