Renpy is just a program that uses Python & has Python support, or so I understand. Renpy's wiki (link here) is what's outdated, you can see by the banner at the top, it's on every page. I keep seeing people using Unity here for the game jam, maybe I should've picked that up instead haha. But I just wanted to make a simple VN so I figured Renpy would be best since it's meant for it.
