Why is there a series for a single game?

For why is it on src, it was accepted back in the day. Rules were a lot more lenient back then and allowed more stuff to be added. And for why is it a series there is only one game, this isn’t the only game in the series, the others aren’t on the site yet.

Oh alright makes sense I guess, I just found it kinda funny how there's a series of one game lol
