Since I had to dive into the archives to get these links >>42786544 I bumped into some memories of how these Jams started. Here's a little history lesson for you anons.

Here's the post that started everything, an anon whose name I never got:

Then here's the official announcement, it was decidedly called "pony arcade" and it was to be streamed at mlpcon:

The stream:

The host then announced his plans for a Halloween game jam:

I think the same anon went on to make a Halloween Jam with the help of buttercupsaiyan. That jam, like this one, wasn't hosted at a con. They had a couple of threads:

The stream was apparently recorded, but I've not been able to find any trace of it.

Marecon passed in February and there was no sign of life from the original hosts. Then came mlpcon again, anons (including me) were asking if there was gonna be another Jam. No one seemed to be planning to make one, so I decided to step up and submitted a panel a couple of days before the panel submissions closed, (I think it was two days, I remember cutting it close):

And made a thread

The announcement was so abrupt, I'm surprised we got as many games as we did. This, of course, was also recorded:

For mlpcon, we had another. "ASSet edition"

I fucked up and didn't actually show off all the games and actually ended the stream half an hour earlier than planned, so I asked for another panel and they graciously gave it to me. That's why there are two streams. (I blame it on the a-a-a-a-a-alcohol. It's why I don't do these *tipsy* anymore)

We then had the "Anon's choice", which resulted in the pony hobbies jam

And that brings us to this day!

I got nostalgic and decided to write what's happened so far
