FEZ was a wonderful game. I really miss it a ton.
There’s a bunch of other games that I used to play a ton that I can’t really recall. I hopped around a lot of different games, and a lot of them had a dying server, so I kinda stuck around the last final moments.
I loved Wizardry so much.
Yeah, i played on the first CBT, after that the game decided to not work on my laptop anymore and after waiting for an answer from them (GRE), none came so i decided to leave it be, they are bad at handling customers anyway.
Grand Chase was one of the games I grew up with, so seeing it close really put a pin in my heart.
dota 1 and diablo 2 server from my country
Well, these games got shut down because of low player count, but I enjoyed them because of the gameplay and the community. 
Neo Online (playOMG)
Pi Story (Aeria)
Luna Online (gpotato)
Exteel 
20characters
Legend of Edda! I love everything about the game! It shutted down but a new company got a license to publish it again but they can’t manage to make good events so it’s a ghost town server now.
GunZ the Duel, Exteel, Metal Assualt, SWG, Wonderking, Archeblade… so many good games I wish were still around. Many have private servers, but it’s just not the same.
Exteel, Metal Assault, Trickster (Though, I could see it coming almost immediately after Open Beta), and I never actually got to try Tales of Eternia online.
Dead for sure: Trickster Online (at least the international server).
Practically dead: PangYa & Uncharted Waters Online.
Should be dead: Ragnarök Online 2.
Metal Gear Online 2
NexusTK: Kingdom of the Winds (ok, this last one is a joke as the server is still running, but it’s had maybe one or two substantial updates in the last 8-10 years or so, so it’s basically dead to me)
ROSE Online. I really like the characters…
Zodiac Online
zodiac envoys, are you guys here ???
Trickster Online, rip
There was just something about the game that kept me entertained for a really long time and made me come back to it after quitting for so many times. The private server was fun for a while but still there was something lacking.
And friends i found in Trickster are the people who i’ve been gaming with for over seven years :3
Grand Chase season 2
Good ol’ season 2 ;_;
Need for Speed World 
Gunshine 
It was shutdown on the 30th of November in 2012. It looks really bad now that I look at it again lol. Honestly, I didn’t like the game at first but the community was really, really nice to me and as I continued playing it, I enjoyed it so much. It’s too bad that they never brought it back.

Infinity Online (the one by Windysoft)
Neo Steam Online
Luna Online
Ragnarok (died for me with Renewal update, also they recently closed official servers in my region due to lack of players)
There are bunch of others that gone bad either with some ‘big’ update or by publishers’ monetization.
Peria Chronicles the other mmorpg i was hype for if IMC failed my expectations has no new news since 1945. I’ll pretty much considering it dead.
Animu Sandbox action mmorpg with heavy pet raising mechanics…who isnt sold for that!
is it still alive?
