This idea would certainly help to keep games from going into oblivion before the world passes through a 24 hour cycle. I was under the impression that this was being followed, but recently that hasn't been the case. New games, if they are lucky, last 1 day, 5 hours! I personally have unpublished games and I wait until my entry disappears before I publish a new one, so everyone can create.

(Oops: sent before I finished)

Anyway, sometimes my games last for a couple of days, maybe even 3 in low-traffic times. Other times, they are gone in less than 24 hours.

It's hard to predict what times will be high- or low-traffic, but as time goes by, the low-traffic times become less common.

Actually, there is something kind of like that now. When you get to the info page of any game, there is a "related games" area that shows you 3 games from the same area (science, geography, history, etc.)

In the upcoming upgrade that section will remain, and will be augmented by a section on games by the same author.

Not fully random, but if you're playing a game in entertainment, you'll get more of the same subject to pick from.
