ive tested the economy, there is none. there are no materials to be found, a player has to now, open a port, build some forest, harvest them and close the port and move to another port to get more materials.
but the "nightflips" are the same regardless, you go to sleep and your port is gone, which is no different that going to work and coming home to find your port gone. but by splitting a low turnout server into 2, you now has less people on both, and less people willing to sail for hours looking for mats or ppl to engage. neither solution is going to work. if you have nobody to fight, before long 1-2 nations will rule it all and then what? cry because there is nobody to fight because all the smaller nations will just quit the game.
