Dunno if this is allready on here but there is a free BS game out there made by fans.. played it a wile back and its good as hell.. It follows the same 2D backgrounds and animations as the first 2.. check it out at www.brokensword25.com
yeah btw.. the voice acting is in german but english text..

Already mentioned here
The puzzles were quiet entertaining but the story really doesn't feel like a continuation of the BS series to me, it uses the same characters but the plot drifts wildly away from the established storyline and some NPCs act 'out of character'.
