KND Operation B.E.S.T. - Shutdown due to ending
CN's Fusion Fall - Shutdown, brought back from the grave by dedicated fans and shot down via DMCA takedown... which kinda sucks, wanted to play this one to the end and see all the more gothic-ish character redesigns... I mean, it's Cartoon Network's shows, just in a more unique style.
Toontown - Shutdown by Disney, then resurrected and kept online permanently... Which is a huge surprise; When Disney hates or no longer is interested in anything, they shut things down pretty hard. The original creator saw potential in it and bought the game from Disney, the rights, it's assets, everything and rebuilt it to Toontown Re-Written. Battles are turn based, though attacks are based on items as you need to purchase gags to fight cogs... which to me is a bit of a downer, but it's still fun, even as I became an adult.
The Mana World -
Found this when I just wanted a basic MMORPG without 3D graphics, cleavage and deal with furry's or Isometric views. The mana world is as basic as it got. Basic graphics, basic setup. The game was developed as an engine to run other MMORPG's, you could easily download the source and build your own RPG from there.
Guild Wars 1 and 2-
They we're good games, enough said.
Flyff - Shutdown, then revived by the Die Hard Fans
This was another basic MMORPG, but it was one that was... for a free MMORPG, a lot of fun. More fun than WoW or Guild Wars 2 or even Final Fantasy 14... Why? Aside from being able to fly, the creators gave a sh*t about the events they ran in it. A prime example, you had a massive town setup that could get attacked. Meaning monsters in the game world would invade sanctuary areas, they referred this as a Monster invasion where if you wanted your safe place back so bad, you had to beat the sh*t out of them and get them off your front lawn.... And the combat is as basic as it gets, but this was a free and fun MMORPG.... I just hated that you had to reach level 20 before they would even let you ride a hover bike... Eh, I'll post more about it in my Topic and massive list Games Obscure.
