Wow, didn't realise this game was that old, the game should of got a lot more publicity than it has, I've only really noticed it since it's gone on the App Store for Apple products.
It's a shame really, because somebody like you, or me, who started the game fairly late won't ever be able to be the highest level in the game (Unless there's a cap? Which I doubt there is, and imo there shouldn't be) which is a bit frustrating really. I think there should be other ways of gaining managerial levels other than just getting promoted.
I drew in my league game today, which is disappointing, I was going to watch the game to give myself more possession, but I was asleep haha. But still, I'm en route to be undefeated in the league, aha! Always good to be ambitious I guess.
