Your analogy is not very precise, because I didn't say "met what's the point in training players for other tactics as LI is the best anyway". No, I didn't say that. I said "I know tactics are balanced and I want to train players for other tactics, but I don't know how exactly and I don't want to waste 5-6 seasons of training only to discover I haven't trained players the right way".
I mean, every experiment takes at least 3-4 seasons if training is involved (and it should be, as most players on TL are trained LI style). If this was the only massive multiplayer manager game in the whole internet, you bet a lot of people would try. But people don't want to spend a year or year and a half only to discover their work was for nothing.
I want at least some hints, like "Driving is the most important skill when Game Engine is choosing which player will take most shots".
As for your analogy, Colombo didn't sail with intent to find a new continent. He sailed to find a shorter way to either China or India, I can't remember which one, to shorten the trading route. The fact he stumbled on new continent was pure coincidence.
