I wouldn't blame you if your reaction to the announcement of Trenched, Double Fine's downloadable tower defense title, was entirely non-plussed. "Wow, how original." After all, this sub-genre of strategy games is approaching -- or has already reached! -- full saturation. I would blame you, though, if you didn't give it a chance, because it's honestly a desperately needed breath of fresh air in the genre.

It's not just that Double Fine's trademark wit and humor is evident in every facet of the game's design; Trenched a seriously polished and surprisingly deep game, too.
