I have been a Warcraft fan from day one, when my small, young and eager hands got hold of a copy of Warcraft: Orcs and Humans. Back then I didn't have so many games to choose from, so I guess I played it at least three times (Demon/Water Elemental spam 4 teh win!). Warcraft 2 I played at least two times, and Warcraft 3 three times again.
Yet I never touched World of Warcraft, at all. I was intrigued at first, but when I started hearing about how the MMO mechanics work, my interest faded fast. I much prefer enjoying a tailored single player experience to the streamlined multiplayer questgrinding typical of MMOs. Also I like to play games in my own sweet time and not have to make appointments or reserve a regular time slot for that. This creates a pressure to play, which completely sucks out the fun for me.
Also, I don't like how MMO's "feel". Recently I tried the Elder Scrolls Online Beta, and movement and combat in it is so "floaty", it makes everything feel fake. You can walk through NPC's and most of the items and objects in the world are static, as if glued in place. In single player Skyrim dishing out and receiving blows actually feels physical, NPC's get in your way, items can be moved around... the game experience is just vastly superior.
The only MMO I spent some considerable time with was The Old Republic, because I heard that you can essentially play it as a single player game and that it has a very good plot. Both of these are true, but the technical shortcomings of being an MMO persist. I also don't like the monthly subscription model. I wish companies would charge me for the amount of time I actually play. Sometimes I can only play a game for a couple of days a month, because I'm on business trips or have other assignments. Then the subscription I just bought is almost wasted, discouraging me from buying the next.
I guess MMO's are not ready for me yet
