For quite a while genre mashups have been, as the kids say, the bee’s knees. Taking existing genre tropes and pushing them together have given us classics like Deus Ex and Bioshock. They’re a great way to bring in cross over appeal across multiple audiences and allow players who wouldn’t normally touch a genre to find out what they have been missing. Infinite Interactive struck gold with Puzzle Quest when they mashed up Bejeweled with a fantasy role playing game. Developer Rebusmind must be big fans of the concept, as they have switched the idea. Now Pipe Dreams is the game being dropped into the RPG format with SwapQuest. Surprisingly, it works quite well.
