Remembered about this soft that I got years ago…
Osaka Simulator
An Osaka simulator! (from Azumanga Daioh)
I think YouTube didn’t even exist back then… and I remember getting some beta version, so I don’t even know how the game is today.
Osaka Simulator
But anyways, it was developed by Hirahira.net, a company that today has other “games” based on the same idea.
Osaka Simulator
Basically, you have Osaka-san and her room on your desktop.
And you only watch her do random stuff, since the only interaction available is when you get to buy more random items for Osaka to interact with.
Watch the videos to understand better (or worse):
Kasuga Ayumu Mail Order Life 3D
Osaka Simulator FINAL clip

Long video of Osaka Simulator
You can get the soft on Hirahira’s oficial website.
Or, if I’m not mistaken, a translated version on DoujinSoft’s Osaka Simulator FINAL website.
