Couple of things:
First, I understand an app may help the appeal of the game, and that's a good thing. I just don't want to divert attention away from improvements to the game itself in favor of an app.
Second, my understanding is there hasn't been a lot of attention given to changing or improving any of the games on WIS.
I've been a member of this site for quite some time (over 10 years) and can remember when it was sold to Fox Sports. Those of us who had already been playing the games for years were excited as we assumed such a large organization would no doubt provide the marketing and advertising to send the number of members playing the games skyrocketing. Obviously it appears that didn't happen.
Even back then, though, there were periodic updates to the games, including HD (which hasn't been around nearly as long as some of the other games I've played). Now it seems there aren't as many updates.
I will say, however, that HD has always had (and still maintains) more players than the NBA simleagues games, which means at least as far as basketball goes, it is still drawing its share of attention on this site.
From what I've seen, the games that seem to make the most revenue on this site (i.e. get played the most) are MLB SimLeagues and HD.
I can see how this game might get stale for some people, but I'd imagine you need to have a great deal more teams than I do for that to happen, at least for me. I played the game from the time it first launched on here for several years, then took several years off, and am still enjoying it now. It could improve, but even as is, it works to entertain me.
