RPG MAKER lets you create an original role-playing game without any prior specialized knowledge or training. RPG MAKER XP is full of the functions you've been asking for, including game data encryption and a scripting feature that lets you change the very heart of the RPG MAKER engine.
There’s also a bunch of other discounts on RPG Maker engines & games available on this Steam page
It runs fine! :)
32-bit Windows programs can run on 64-bit Windows just fine thanks to WoW64 (with probably very few exceptions)
