I agree with removing gem gens, but some nations will need to get compensation for that. Reducing the cost of Kailasa summons that someone suggested is a good idea. Other nations need similar boosts.

Banning some nasty globals like AN or AC is also a good idea.

A map for 12 players is the biggest I've ever played, because I never wanted to own too much provinces in the late game. A lot of larger games break due to players losing interest. I'd say 12 is a good upper limit.

With other things I don't agree. Low gem income is not a good idea. The problem is not in abundance of gems, but in the fact that CBM makes some spells too cheap.

Also, removing higher research levels would remove much fun from the game - bad idea. For the games where you want longer midgame, just set difficult research. Personally, I like the pace when games reach endgame sooner and finish sooner.

There is no need to ban any nation, unless it is considered overpowering. Just don't pick the nation you find needs too much MM. In RAND games, you should be able to give a list of nations that you don't want to play.
