I’ve been a fan of the RPG Maker series for quite some time, though I do wonder why RPG Maker 2000 costs more than 2003 (Although it does cost less than VX Ace at $60)
I’m not really sure what else I should say, 2000 is effectively 2003 missing a few features, though it would be nice to be able to use the 2000 assets in more recent versions of RPG Maker would be nice.
If you want to, you can find it on the RPG Maker 2000 steam page.
