Well... are you going to join the guy EVERYBODY knows, and likes on the forums, or some Joe Schmo that just joined?
Glad you asked. I'm being completely honest when I say that I'd much rather join a new player than be guaranteed a spot in Wakko45 or A J Yusi's customs. New players are usually more willing to share the leadership, which I always like to have. Their customs are more laid back, and don't feel as... formal, like you're in the presence of some really important person- the host that everyone knows. Smaller customs are more flexible, and you're not on a rigid schedule. There are a few more reasons that I just can't put my finger on...
Besides, it doesn't really take
that much skill or experience to host some fun customs. You just throw some games on- the ones that everyone likes, and maybe mix in a few of the hosts' own maps, or maps from the players in the lobby. If you're not sure what to put on, ask the players. You might not know it, but most players are very capable of hosting good customs.
There are a few exceptions to this. For example, back when you used to host your daily race lobbies, they were the best place to go for anyone who wanted to race. You had all the race maps, and you were able to keep the games flowing smoothly. Basically, whenever someone wanted to race, your lobbies were perfect because
the goal of them was to give players the racing experience they desired.
That's not necessarily the same for the other gold hosts though, who don't really have a goal, other than to have fun (which is the goal of all customs). If you're looking for a place to just play through a bunch of minigames, then they can be exceptionally fun. But for those who want diversity in their lobbies, the big ones won't always satisfy them.
I can partially see your point though. If there's a really experienced gold host who's hosting just minigames and a newbie who's hosting just minigames, I'd probably join the gold host. If there's an experienced gold-host Tomtris who's hosting race customs vs a newbie who's only playing race, I'd join tomtris. (I wouldn't ever be the 40th person to RSVP to any lobby and be way on the back of the waiting list just for the experienced host though.) But I'm not always looking for just minigames or races though. Smaller lobbies often offer different things than the golden guys.
But that's just my opinion. I can perfectly understand how others prefer golden lobbies over regular ones, and I don't really have a problem with that. The biggest problems occur when the RSVPs for gold lobbies get way too high, when the players further back on the waiting list are "wasted." I think the limit idea I proposed could help solve this.
