And about the subject of this thread. I'm using 1.23 just because you actually can play online with it, you could do this with TSF and C-C also, but nobody is playing it these years. And because TSF and C-C wheren't released outside Europe, it's better to make all of your levels 1.23 so everybody could play them. So I recommend the normal Jazz2 game (1.20 to 1.23) to everybody.
