There's Game Dev Story and Hot Springs Story. I think a game based on making phones would be interesting, you'll hire engineers to research features and design on specifications of your phone.
An obvious one would probably be about hotels. But one I would love to see is one where you run an amusement park where you get build rollercoasters and place them where you want like HSS.
Just the other day I found this page that shows a bunch of the games Kairosoft made in the past. I'd love to see all of them translated, but especially the Japanese town one and the Store ones.
I think they should remake GDS and the other top selling ones with current technology. Im not sure if I'd rather see a few remakes first, or a bunch of ports
Lol when I saw the "Port Management" game i didn't look at the screen shot so I'm thinking "lol a sim about porting games" But I would like the mountain town one.
i want oppressive alien regime and feudal mountain town ported over. those are the most interesting to me.
Pop Idol Story would make sense if Kairosoft sticks to a Japanese theme. Whatever concept Kairosoft comes up with next, I'll be among the first to buy it. I'm a fan.
