Theres no game yet with this variation of code, its to soon.
But theres been quite a few games use other variations, only most of them aren't complete games.
But heres some that are complete(at least downloadable)

1) Pachinkoagogo
2) Natio (hes got some bugs in his game, the strange entries are nothing to do with my system)
3) FingerBang
4) Christmas Crisis 2

Of those games I only made one, so you see that people do use this stuff.
