Awesome, thanks! I had not heard this yet. Very cool. I think GT is a very fair mod, it's just a slower progression through the game. For instance, yes, at the beginning you can only get 2 planks per log, and 2 planks only gives 2 sticks... but that is incentive to make the saw as quickly as possible.
Unless they are re-balancing it towards more like how it was in ultimate. Back before Greg started messing with vanilla.
