To add to what Seth said, combat systems, stats and all that get really annoying. I could barely stand them in DS and Mommy, and those were written by some of the best authors on the site (dont think anyone writes like BZ, which is pretty much the only reason I sat through the combat in DS. Picking attack agressively all day doesnt suit my fancy, lol).
Just do what countless authors before you have done, and use variables or dont use them at all. Fancy scripting doesnt change much, it just dresses the game up in a fancy binder. (#madgleeism)
