Is this the most OTs for a single game? I know some community threadcounts are larger but they are to an entire franchise as far as Ive seen.
I did some research for the OT11, which
you can find here and had some more stats contained within if interested. But to your particular question, I did my best to research it and this was the most fair comparison I was able to come up with (note obviously we've incremented by 2 more OTs since):
If you add up all the Halo threads for individual games before the franchise OT it obviously makes the Halo bar much bigger, but then, that of course is combining both a full franchise and individual games' OTs while only the former is still incrementing. But it's worth mentioning of course. Compared to any one individual game, based on my research Destiny is #1 with a bullet, and only the Halo franchise community OT sees similar activity.
Halo reach had over 20 I think
I searched pretty extensively, and so far as I know- we're counting just "OTs" here, again- Halo Reach had 7. The Halo Franchise OT is currently at 21 though, and so far as I can tell, it really did start at 1, and the OT1 was in January 2012 (though its contents span the full game series' which is why I used Halo's original launch date for the purposes of comparison).
