Im selfish and only play SIMLeague Baseball and have since 2003. I think the game in general runs fine but a couple of things could address the decline.
Can you publish the active users (those who have had a team over the past year) for each of the products? Point being if one of the other sports is outdated and not paying the bills, then lets not penalize the larger apps while it plays catchup. The strong survive, the others have to go.
For SimLeague Baseball, I think a few quick query improvements in the draft center (aimed at making it easier on progressive drafts) would really make a huge difference to the Commissioners....and possibly encourage folks to do another team. I doubt that is a huge cost as it doesnt touch the engine.
Fix SimLeague Live....while I never played in a lot of live leagues, it is very entertaining to crack a beer, chat w/ owners, and test concepts or play games...that may build some more comraderie...
Agree having a large corporate running this probably wasnt great, hoping these new guys have some cash to put back into it....the above wont require a lot.
