So, I used the very first RPG Maker 2000 back when it was released, even if I switched to 2003 soon after. Decided to join after seeing the MZ "(un)reveal", and see what I've been missing since 2003.
I see a number of things haven't annoyingly changed, like arbitrary integer values for XP...
Revisiting one of my older projects in a long time to work some more on the mechanics. I've been working on- and off-again for about a year now on recreating the Force and Mystic systems from Wild ARMs. And I think I've finally made some good breakthroughs on that!
Still, it is not perfect and I may post my thoughts at a later time to see if there are any other suggestions or alternatives I've missed.
