OK as someone who only ever really plays MMOs, I will throw in my opinion, for what it's worth.
As with any game, it will always come down to personal preference. However if you have never played an MMO before then I would recommend WoW. It's the true entry level vanilla MMO and it's very easy and friendly for newcomers. I would play that to lvl 20 (it's free upto then) and that will at least give you an idea of how these games work.
If you like it then you have a choice to pay up and continue playing or try another.
The big guns really are Star Wars The Old Republic, Rift, Elder Scrolls Online, Guild Wars 2, EVE and Wildstar. Then you have some more like DC Universe Online, Neverwinter, Marvel Heroes, Everquest 2. If you like the fantasy setting then Rift and Elder Scrolls are both good solid games. ESO does require a monthly subscription and it's very poorly received with just about every man and his dog
****ging it off, which I think is unfair. It's a decent game that just has some shortfalls.
EQ2 is more for the veteran MMO player who likes things old school. I enjoyed it for quite a while when it first came out, but now it's hard to really recommend it.
Guild Wars 2 is great value for the cost. One off payment for the game and no monthly subscription. Really cool game but it did get boring after a few weeks for me, but I do often go back to it and play it for a bit.
Rift is good for FTP but as with EQ2 it does already show it's age, but hey it's free, so why not try it.
Wildstar is not my cup of tea. Not a huge fan of the look and style but it seems really popular so I am in the minority on this. It also currently has a monthly sub and unless you have a trial key, there is no way of giving it a go without buying it.
EVE Online... Oh boy. This is a game that I just wish I liked. I love the fact it has a hardcore following and I just wish I could be one of them. I try over and over to like this but it's just so hard to get into as a new player. Overwhelming doesn't begin to cover it. I would never
**** it off though as clearly it is a decent game if it's your thing. I just wish it was mine.
My current favourite is Archeage. It seems to have everything that every single one of those games mentioned has in it. It's currently in Alpha stage though and it costs £110 to buy premium status which allows you to play right now. It's worth every penny in my opinion, but that is a lot of money.
MMOs take a lot of investment to get the most out of them. Nearly all of them have some form of quests, levelling and crafting to contend with and they can easily eat away months of your life. They are also the most rewarding games you will ever play.
I envy that you have never played WoW. I would love to go into that game fresh with no knowledge of it. If you like it, just say goodbye to about 18 months of your life
