I am the same way, and I can list which games I have played. FFXI was my very first MMORPG, but I also played Phantasy Star Online EP 1+2 on the Gamecube, but never played it online until i played the private server last year.
So from FFXI.

Though, I have to admit that most of these games were really enjoyable, but I have stopped playing most of them due to the release of FFXIV, and I cannot find myself to download these games again other than the other two games I am currently playing. If i were to download any of them again, I would probably check out Perfect World.
I also have to include that a few of my friends have recommended Guild Wars and the upcoming Guild Wars 2. I would like to try GW2 but am flustered about the story, and if I should play GW before GW2. Everquest was also another recommendation but I can't find myself to play it. lol
I also do not play very many streamline games like Lord of the Rings Online, or Star Trek, or Star Wars. I've always disliked video games based on movies or books. Besides Scott Pilgrim vs. The World. That game is awesome xD
