FFF (Final Fantasy Forever) was very good. Problem was they made it too strict and never finished it, but it was still one of the most noticable RPGs ever for WC3.
Final Fantasy Open RPG is poor and is one of the worst RPGs ever as it is riddled with bugs, rips and imballences.
Final Fantasy Epic RPG was a good RPG and showed a lot of promis, but the make gave it to someone else to continue who was a total noob and so the map went down the plug hole. From one I would recommend, it is one I do not recommend unless you play the older versions still made by ILYAS.
COT rpgs are fun with a group of friends, but bugs and imballences make them not that recommendable for multiple play.
Heroes and Empires is a good non save RPG as it is also a RTS and a coop or PvP.
TKoK is a good RPG, hard to get used to and quite slow, still has to be one of the best ever made thou due to the ballence and detail.
You also get other minor RPGS which are fun for a few games, but never really more than 15.
