Default, but as I said if a majority of voting players wishes otherwise I am willing to change the settings. Although actually personally I would prefer slightly higher gem settings than default for ma, so I will change the op to reflect that.
I would also like to add that this game is open to players of all skill levels. I myself am intermediate at best. So if you'd like to play a mod nation in an mp game, go ahead and join
There are not many opportunities to do so, though admittedly there are a few mod nation-accessible games going on at the moment.
