Okay, so in terms of games played each day, the picture is definitely not one of decline.
Since game IDs are incremented by exactly 1 with the creation of each new game, we can use a set of known games with known start times to determine how many games were played within a period of time. For example, we know that there have been (highest game ID number ever - lowest game ID number ever + 1) games played in the history of Warlight.
We don't need every game ever played, we just need a large enough set that we're able to look at things day-by-day-ish. So I used the 1v1 ladder. And since the API doesn't give me the exact start date, I instead used the time the pick stage was finished in each game (which is typically between 0 and 3 days since the game was created). This doesn't create much of an issue as we can still see the approximate trend.
Here's what it looks like:
Clear growth here, a bit more exponential than linear. Certainly not stagnation (or we'd be seeing a graph that's concave downward, not concave upward).
This one's a bit messier, but it's closer to the "derivative"- it's the highest ID of a 1v1 ladder game recorded for each day minus the highest ID of a 1v1 ladder game recorded the day before. As you can see, the inability to get the actual start time kind of fuzzes things up- some games end up registering for their actual start date, while others end up registering 3 days later and making the day's count look higher. Vacations are probably what really scres up some days.
But while a tad fuzzy, it clearly shows general growth- the number of games created each day also looks to be increasing by a slight margin.
What's interesting here, though, is that the biggest jump in games created happened in late 2011- right around the peak in Google Searches. So it seems that Google Searches better reflect growth than they do the size of the community. We're not seeing the drastic growth of late 2011 anymore, but that makes sense as the site's matured a bunch since then.
In terms of game creation, WL's best games look to be ahead.
