One of the big problems were the generators. They are so slow at the beginning, no action can happen without one person just sitting on them. Even after that, the prices for most iron commodities are overpriced, which makes the game even slower. Also, once one goes to middle, the diamond generator is also quite slow. I suggest buffing it a bit, and having more around the middle. In addition, also have other types of generators at middle. Also, after I think 4-5 minutes, there is a generator upgrade which makes everything super fast and harder to upgrade again. So, maybe up the generators from a start to like, one iron per 1.5 seconds. And like, 25 iron to get it to level 2 and 1 iron every 0.75 seconds.
