EQ on E'ci from 99 to about 2003. Merged at some time after I left into Tunare. Different guilds but only remember Amber Order and Final Evolution
EQ progression server Fippy : 2011-2012, left with PoP release because I found that the expansions were released much too fast and I didn't like the post PoP EQ anyway. Guild Ascendency and a few others that failed one after the other because of the expansion unlocking speed.
VG : forgot the server and no guild
LOTRO : on and off from 2007 till today on Estel (French RP) and Belegaer (German RP). Forgot all guilds but Les Cavaliers Solitaires on Estel.
P99 : guild Europa for a time.
I won't mention the dozen + of others MMO I played (Daoc, EQ2, Aion, Conan, AOL, Wow, SWTOR, TESO, Archeage etc) because none has left any impressions Worth to be remembered.
For the sake of brevity I have listed the characters I played the most in the games I played the most. Chances are if you played an MMO with a Medawky - it was me!

I have also played Rift, STO, SWTOR, GW2, Neverwinter, WoW, DAoC, Lineage II, Asheron's Call, AoC, TSW, and if you want to go really far back, Utopia, M59, UO, and Shadowdale MUD. Names were usually one of the above. It's super unlikely anyone would remember me from those games though, for various reasons :)
I've played a lot of games, but kept a pretty low profile and mostly just played with my family. In EQ1, on the Rodcet Nife server (later Quellious and Povar), my family started the guild Tul Acharn, which, last I knew, is still alive and well to this day. Later, we joined the Order of Manveru.
The only game people might know me specifically from is DDO:
Server: Thelanis
Guild: < The True Path >
Character: Nikibrik
Alts: Brogburt, Rubrik, Capricio, Kallistie, Thorbim
