Question about Moonstone Tavern

Is this a sequel to the one on Steam or an HD remake? Should I wait until the new one comes out before I buy it?

I love Game Dev Story and I can’t wait to see what you guys come up with next, keep up the good work!

Actually, GHG only developed and published Game Dev Tycoon. And they’re in the process of developing their second game ‘Tavern Keeper’.
Game Dev Story was made by a company called Kairosoft and Moonstone Tavern has nothing to do with Tavern Keeper other than that it has the ‘tavern sim’ theme. If that’s what you mean.
