Seems interesting to allow you guys to directly request certain stat IDs, if you know you want them, given the data-heavy nature of the webservices, and I think it dovetails into another feature on my backlog to allow you guys to request the base stats for composite stats (ie, if we return ERA as a stat, also return Earned Runs and Outs). Don't expect a quick turnaround (we manage to keep busy here :) ), but this is now on my radar for maybe the next month.

I second the request for game played. Also for games projected.

Oh, interesting, I might have misunderstood here. I was considering the problem of displaying composite stats -- for instance, in basketball, you might see that a player has a 95% free throw percentage, but you might also be curious what his makes vs attempts are, ie, is he at 95 out of 100 free throws, or 19 out of 20? So it made sense to me as a feature to offer the option to get the base stats (Free Throws Made, Free Throws Attempted) along with any composite stats (Free Throw Percentage) that are shown.

It sounds more like you're asking for the ability to separately request that you'd like to specifically see the Games Played value, ie, the total number of games that a player has participated in over a certain period of time. We typically only show this in aggregate for your team on the Full Standings page (using Baseball as an example), or on the team page in the Maximum Games module (at the bottom of the page). Is that what you were wondering about? I guess "games played" part could be solved by allowing you to request arbitrary stat IDs to include along with your request; the "games projected" part is a bit trickier as we don't really have any way to reference that (it's not a stat, we just calculate it on the fly).
