Old or New Games

I was recently asked if I prefer to redo old games or create only new one. When designing a new game I look at old PC games, board games, arcade games, sports, etc. for inspiration. I've released Farkle and Triples, both based on older games but reinterpreted for the Palm and Pocket PC. I gave them a new twist by adding additional strategies. My two original games, Word Watch and WordPop! were both inspired by older games that I think did not go far enough or offered limited replayability. WordPop! was actually thought of after I was playing a math game. I liked some of the strategies and believed they could translate to a word game. I am interested in creating games that have several strategies whether they are original or based upon an older game. I still feel challenged and motivated by both scenarios.

How are inspired? Would you rather play old games or try new ones? Drop me line as I'd love to hear your thoughts.
