I wonder how many social lives will be lost to Glitch once it goes public. When I first got the Sims 3 I missed a few nights of sleep over it. I would've done the same with KOL too, but the turn limitations saved me. Makes me think it might be cute if Glitch had an event that occurs when you've been active for a certain period of time. Mr. Rock says "Hey loser, did you know you've been playing for 13 hours now?". Anyhow I agree that more test windows even if they're shorter would be pretty sweet.
i think the current testing intervals are good. every week or two.
it makes more sense to have significant changes between each test, so that we can actually test new things, as opposed to replaying the same stuff again and again. the point of of these tests is to refine the game, and i think it would be more difficult for the devs to refine the game if they had to constantly monitor tests.
that said, some weeknight tests would be beneficial.
