I am Japanese and I use a machine translation, so I apologize if there are any difficulties in reading.
I am a Fences3 user for Steam.
I saw an article on a forum that there would be a notification of an upgrade option when the Steam version of Fences 4 is released.
So I didn't buy it and waited for the Steam version to be released.
But today I saw that the price of Fences4 on Stardock.com has gone up a lot
If I hadn't seen that post, I would have bought Fences4 as soon as it was released...
If the Steam version is also released at the current stardock.com price, I will feel cheated.
