I'm happy to say that Mutant accepted my idea to cap the number of free turns from items per day. He's stating 250 will be the max. This will level the playing field a little, and will put a limit on how time-consuming the game can become, plus will mean more +turns items available for everyone else, since they won't be so hoarded.
Also, he's saying he might put a hard cap on the number of mayors per player, probably 20 each. You can probably tell, but this will only impact on Staberinde at the moment. If it goes through we should consider targetting the outlying Staberinde cities in our area, since the two main players there won't be able to maintain the > 20 cities they each have now. So everyone keep leveling up.
I tried a level 4 dungeon because I was going pretty smooth in level 3's and barely need heals now. It was a bad mistake. There is a huge difficulty cliff from level 3 to level 4, i got my ass handed to me, lots of deaths, used 90 heals in 20 minutes, cost me ~$15000 in ressurections. And I ended up gaining XP slower than before due to running away. So, even with a pile of extra heals, level 4 dungeons are too hard for anyone under level 20, which means level 3 dungeons are all you need for training up guys to level 20.
