Out of Pod Experience

EleMud back in 1998-1999 (muds were proto-mmo´s back in the day, man this MUD ROCKED HARD back in the day! So much evil pvp!)
Everquest (2000-2004 , then short bursts throughout the years up to this year inclusive)
Everquest 2 (2004-2007)
Vanguard:Saga of Heroes (2007-2009, very short bursts until 2012, I still cry a bit over it ) :(
City of Heroes/City of Villains (2005-2007 and short bursts until it closed in 2012)
EVE Online (Been here since 2005, will probably be here until I die or server dies, whichever comes first)
Tabula Rasa (2007 until it closed down in 2009)
LOTRO (there since 2009, lifetime sub, still play occasionally)

Rest is the usual crap I tried for a couple months and got jaded/bored

Anarchy Online
DAOC
WAR (man I miss that game, it had so much potential)
RIFT
Defiance
The Secret World
Guild Wars
Guild Wars 2
Path of Exile
Fallen Earth (I miss this one, but it went downhill fast)
DDO
STO
DC Universe Online
Age of Conan
APB Reloaded (ugh)
Pirates of the Burning Sea (damn you Thalidar for making me waste money on this one lol)
SWTOR (I was bored and was already F2P, even more UGH)
Requiem: Memento Mori (this one was actually pretty interesting, haven´t checked it in ages, might still be worth a look these days, I remember it having a unique way of gore back in the day)
World of Tanks (played it a lot, then uninstalled, couldnt keep me hooked, it was a nice stone to anchor myself when EVE was truly depressing, man EVE was really dying back in the day, lots of other eve players there too, gudfites! but then EVE turned out for the better)
Realm of The Mad God (I blame STEAM)

And after that the stuff I probably choosed at random off MMORPG or STEAM and installed and then uninstalled a couple hours later or a few days later :)

On an extra note I will check out ELITE: Dangerous next year when I get a better puter, there´s so much lack of real interesting Space MMO´s or games whatsoever plus I kickstarted Star Citizen, so waiting on that too.

Cheers!
