I think Rumour wanted the opposite of that, not working within small time limits but games in which certain developments proceed slow, so that it's sufficient to check the game every 30 minutes or so.
I think there's plenty of browser games that work like this. I remember playing one myself; you could build up a space fleet and conquer planets or something. Certain upgrades needed hours or days to be researched. Unfortunately, I don't know what it was, and it's certainly not online anymore. But no doubt there's hundreds of games like that on the net.
