Don't remember the exact number, but I once had it up to the 80-ish range.
7-8, but that was when I had 5 runs on hold for a couple of weeks while clarifying an aspect of the timing. At all other times, it's topped out at 2-3, to the best of my recollection.
I think that was 6 or 7 when I took over Star Control 2. I moderate games with low activity, so usually there aren't many.
I had a queue of about 150 in Laminate Pieces once, I didn't even mod the game before hand but all the other mods left and I volunteered to take the queue (along with another person)
When among us was added, we would get anywhere between 40-60 runs a day, so the most I saw was around 220 in queue at once.
I've had about 400 runs when I was added to Pou as a mod and I've been added to Angry Birds recently and have had about 640 runs
I'm not sure how many runs I get per day
Edit: Pou might of had more than 400 runs
Here's another screenshot by me :o there are also a few Granny runs in there aswell lol
iirc it was something along the lines of 700-600 ish (might be incorrect) when hypixel was at it's peak and i was added to pou
I think when DOOM Eternal launched we had somewhere around 80 when the embargo ended
I like your pfp vegas
