Yep, this game is quite involved and quite detailed - for a boardgame.  But it's not JUST a boardgame.  You can play solo with 1-4 characters, or play with other individuals each commanding one character.  The game has rules for scaling the adventures to the number of players so you'll actually have a chance of winning.  Only a chance, anyway.  Even having lost many games, I still had a great time trying to get my heroes past dark events and combat with strange, fierce monsters!
