A lot has happened while I was sleeping on here... First of all, I'll do the clean-up of established and proven facts that are being debated.
First of all:
Of course, it is possible to start it, on paper. It works, signs are there! But if it happens, games won't have activity because the SAME people will be on two games (and three threads, in this specific case). So what will happen is that games won't be enjoyable for most players, and it is literally the system's job to make games: 1) played and 2) fun (that's the short version).
This is answered by the answer to this. It's pretty simple: a large majority of players don't multigame. Therefore, we can see each player as a value of one, that goes on only one signup. So, if we have 1 setup for 14 players, for example, and we have a playerbase of 20, in general. There is always at least one person who is busy because real life, so let's say 19. The 14P setup will be full in a short time, and people will play and enjoy it. Then, we put a 10P setup (example again), and the dead, and the people who didn't sign for the 14P can sign for the 10P, and everyone is happy, plays a game, etc. If there is a stronger demand in hosting, people can still post their signups, so people can STILL sign and plan their stuff, but there's one game that starts first, and there's no issue. However, if there are 5 games free at the same time, it's chaos, people don't know where to sign, and setups take years to fill. It's not an assumption, it's simple math: unless one setup is really GREAAAT and everyone wants to play it over others, which doesn't happen often (therefore you can't base a system on that), the signs will be spread over the 5 signups that are open, therefore none of them will fill before a while. Of course, it wouldn't always be like this; but it would OFTEN be. Would it be the end of the site? I don't know. It could be, if the scenario I put there happens too much. And the advantage of this system, which is more choice in setups, is minimal, since there is ALREADY choice by just signing for what you want to sign for, since there are more than 1 signups, now. There's a reason we aren't rushing it: it would harm the game flow and/or the game quality, and that is an absolute.
Now, I don't say I want no change at all. I want to improve what we have... which brings to the next point.
That's scummy... I already did that several days ago lol, and I keep doing it.
There you go. It's based on what a system needs to have, it's explained and all.
As you can see, it's inspired by the current system, without being the current state of the site. It's what I mean by "not throwing the current system in the garbage pin".
