Actually, for a game where the strategic aspect is more prominent than usual, I sometimes play large single-level maps with a large number of towns and players (and if you also limit the maximum hero level to 15-20, it turns out that the key to victory is maximizing territorial control, achievable through several strong heroes, whose strength also depends on their army, because it won't be possible to create uber-strong heroes due to the level limit, which means the role of towns increases again, and therefore also mines and resources, which are needed throughout the game)
Um... well, I think I've strayed from the topic - sorry:D
And regarding GSC, what's so complicated about it - you just do it, no problems.
