Brutal Legend was great, but the RTS elements dragged it down a bit. It could've been so much better had it only been a pure hack'n'slash. More interest in replaying it too.
On the average, Deathspank was no worse than Brutal Legend. It did what it was supposed to do, and that's it. Just like Brutal Legend. Tim is not known for bringing fantastic gameplay to his games. Both games had simplistic, workable gameplay that was second-rate compared to the humour and story. Deathspank bordered on extremely childish at points, but it also had some great jokes.
Quest-giver: "Why haven't you finished my quest?"
Deathspank: "Mainquest or sidequest?"
Quest-giver: "Sidequest"
"Deathspank: "ah"
