Soon: ToS.
I have played a few MMO’s over the years. My first experience was with a terribly laggy one called Endless Online. Graphics were majorly pixelated and it was terrible! lol
After that my standards improved a bit 
- Endless Online
- Silkroad
- Secret of the Solstice (Fave ever!
) - Fiesta (didn’t care for it)
- Aion
- Flyff (Another one I didn’t care for)
- Guild Wars 2
- Aura Kingdom
- Echo of Soul (it was ok)
Wow… My list is super tiny compared to most people on here lol The only 2 games I really stuck with for more than a few months was SotS and GW2… The rest were just for a few weeks.
Ragnarok Online and Dragon Nest, two of the MMORPGS i’ve played the longest.
Ran Online and PSO2 for a short while.
Haven’t played so many… but let’s see:
Ragnarok Online - well, before it I didn’t even known that there is something like “mmorpg” only online game I have played was Counter Strike… my friends told me to try it and to be honest I was really hooked :D!
Trickster Online - nice game, but really hardcore p2w 
Wildstar - again, great game, nice dungeons have been really hooked… but some developers decsions made me quit also the theme wasn’t really for me
Tera Online - great combat system… but rest of the game was really boring
Aion - dull and boring, one of the slowest games I have ever played… never again
Guild Wars 2 - great art, great combat, nice story… but dungeons are boring
Blade and Soul - really nice story, great combat system, nice pvp, but really boring side quests and dungeons
And now I’m also waiting for ToS :)…

Haven’t played a MMORPG in years and ToS seems like a good and nostalgic return.
hmm…I forgot some of the early 2000’s other than RO, then I went on online gaming hiatus due to school, then I got hooked on online poker, then I reconnected with RO again sometime in 2010? until 2012…I only play these MMORPGs since then
on and off with
LOTRO
Neverwinter
GW2
actively subscribed to
FFXIV since 2014
tried beta or whatever with
TESO
LEGO minifigures
I tried downloading other f2ps but got tired just thinking how much time I’d waste in a game I’m quite sure I won’t enjoy 
edit: oops I think I raised a dead thread, I was hoping to put up a similar topic but found this one so…
Luna online <-- There’s sort of official comeback for this game. The cbt is currently going on I think. I might try it out for nostalgias 
Wakfu (the beta phase when the game was actually good and more balanced)
The world of magic (smartphone game, so bad and simple, yet somehow nostalgic :D)
And few dozens of others I’ve tried less than a month or two each…
Not mmorpg but I’ve played world of tanks quite a lot too.
what kind of a comeback? is there anything new?
i remember playing that years ago and it was fun
Subagames bought the licenses for that game and the closed beta started yesterday. I bet you could still easily find beta keys for it.
I actually just downloaded the client and tried it out. It still seemed more like luna plus instead of the luna online, unfortunately. I also noticed that they’ve actually added botting button in game so you can bot more easily (yes, you read that right 
). Now that I think about it, something like that might have actually existed in that luna plus update too which killed the game. I don’t have much memories from the plus version for obvious reasons.
I probably won’t bother with this one. It seems like they’ve decided to completely rape the game, unless they change lots of things back to original during/after the beta. Oh well, at least I can use the client to take screenshots of the sprites of my belowed character I used to have 
rip D:
./20characters
