Making DeathSpank was tougher than expected, according to Gilbert -- he started out wanting to make Monkey Island meets Diablo, but the Diablo half of the game was more difficult to balance than he'd thought it would be. Not only did he have to balance weapons and combat, but he had to deal with DeathSpank's own character attributes. A class system was originally planned, but Gilbert wanted to play his character (which originally came from a Flash cartoon series), not yours, so the team eventually went with the "Hero Cards" system.
Gilbert also says he hopes that DeathSpank influences the downloadable market -- rather than simply house reissues of older games or big budget titles, he hopes that downloadable game platforms can be a place for originality, and that "we can get some really good, interesting games in the download space." We'll hack and slash to that!
