I have some vacation coming up pretty soon and I need something to play during that vacation. Now my financial situation isn't as good as it used to be. Therefore I have to cut down on some of my expenses. So I thought that now would be a good time to get to play some of the "older" and cheaper releases. 
 
Now I am a big fan of Psychonauts, hell IMO it's probably one of the best PS2 games. So I was of course looking forward to Brutal Legend, but then the reviews came out and I was not so sure if this was really a game I wanted to play. Not because it got espicially bad reviews or anything, it just sounded like the further and further you got into the game the more it started to play like some rts game, learning you all the basics so you can use them in the multiplayer.  
 
One of the things I liked the most about Psychonauts was the characters and the humor, to me that meant just as much as the gameplay for that game. Also I need to add that I played the demo of Brutal Legend and it definitely had it's charm. But as far as I can understand the gameplay changes drastically through out the game. So I guess my question is: Is Brutal Legend worth checking out for the characters and humor or does the gameplay change so much that it almost becomes unplayable? How big a part does the rts element take up of the main story campaign and is it even worth buying if I'm only interested in the story campaign and not the multiplayer?
