Making them in RPG Maker 2000 seems like a downgrade. For example, I'm guessing that 2k can't map buttons unlike 2k3 where the numbers did stuff.
Well, what are the benefits of coding in 2k3 compared to 2k?
^Not much. I know making footstep sounds is more of a pain in 2k than 2k3, and of course the battle layout is different (though that doesn't affect YN fangames since most of them don't use battles) and a couple of other minor things. What's weird is I've never seen a Japanese fangame made with 2k3, but then here in the English community we're all using 2k3 (AP, the looking glass, TOL, ect.).
Does it make things simple like how Yume Nikki made you only have to just open the program while 2kki is way too complicated?
