I recently re-installed Kairosoft's "Game Dev Story" on my Android phone because I needed a good distraction from the world.
I had to uninstall it years ago because it was shocking how easily I became hooked!
I had no idea they were making games all the way back in 1997, but it makes perfect sense in hindsight: Game Dev Story is a masterful execution of this type of game and might even be a Magnum Opus of sorts for Kairosoft. Even if this type of game is not your cup of tea, it's interesting to check out if you're familiar with the history of video games.
If it wasn't getting late on a Sunday night, I would be booting into Windows to give Bookstore Story a try, but I know if I do I might be up until 3 am...
