Years ago, I had run into an MMORPG that let you accumulate in-game time, so that all the accumulated time can be used in one-go. So, that meant not requiring to log in daily, and instead log in during the weekend and do the tasks. I'm looking for something like that again.

Other characteristics I'm looking for include: browser-based or android-based, travian-style village/city building, free to play.

I have loved Travian, and keep returning to it, despite knowing that it is considered as play-2-win. But even after returning to it, I realize that the one thing that annoys me the most is that it has no concept of accumulating in-game time, and so, after a while, it becomes a chore.

Any recommendations would be appreciated! Thank you!
