atldmat, I'm thinking you're probably missing the real objective of the "game", which is to to try and figure out a way to "collect the 'best' players" you can to win the most games. It's a mathematical/probability game played out over the course of a few months. It's not a baseball game you play (obviously). i could not begin to tell you how many hours i've spent trying to analyze ratings, stats, trends, streaks, etc. in a vain attempt to "solve" the magic black box that pours our a new result every 8 hours around the clock. The game is a marathon and one of strategy - and luck - and trying to find an edge and tip the dice in your favor is what it's all about. So, if it's moving "too slow" for you that means you're not *really* playing the game fully. You could be pouring over box scores, parsing play-by-play logs, seeing what teams that always win have in common, figure out how much range a CF really needs to be good for you in your world instead of trusting the HBD suggestions, how much splits matter versus velocity for pitchers, etc. etc. etc. The variety of data analytic questions you could ask and attempt to answer could consume your life 24/7 if you let it. But, yeah, if this doesnt sound "exciting" to you, then the game is probably not for you.
The reason there's so many open worlds is probably exactly for what Miket has said in other posts: most of the nerds that would be into this type of thing have likely already been exposed to it by now so you're not going to get many brand new people into it at this point. Meanwhile, lots of people like you have come and gone thanks to promotions, bribery by a friend or co-worker, etc. it's very obvious theres way too many worlds and they need to pare the number down to get more filled.
