Because the new Ren'Py requires Windows 10 or above. I agree because I have a decked out Windows 7 computer that I use just for these games. Now I also have to use my Windows 11 computer. It sucks.
Same here, I had an old laptop I used for these games. It`s microsoft`s fault though.
Beside these sorts of "planned obsolescenses" they made a huge mess with their updates these last few years too, even worse than the usual I mean, twice in critical ways and globally.
Some of the problems can be solved by cracks or by emulators but I yet never checked how to do that for Renpy.
As long as it is a de facto monopoly they can keep spitting in our faces. Hopefully Harmony OS or its successors will be fully compatible with most stuff in a few years, Linux has been around forever, but it`s clearly not enough.
