The new rpg maker that has most recently joined the family is rpg maker xp. It has a lot of improvements but some things
have been taken out of it.
One Xp's best improvement is being able to edit the game script which makes it possible to completly change the traditional
rpg maker style game.
Though it is in the rpg maker family xp cannot load the old games from the previous maker because it uses different rtpe
from them. The character sets can be as big as you want them though which is a good improvement, Mp3 files can be played and
the graphics are better.
Sky-247 studios are using this maker to make a new game called Chronicles Of Humia and many other people are using
it aswell to make their games.
The game script language is known as RGSS, Ruby Game Script System which can be hard to learn if you are new to computer
languages but if you are experienced you should find it easier to learn.
This is probably the best rpg maker there is at the moment.
