I got to about the third day of my 7 day Wildstar trial. Tried a few different classes. I love to quest and explore but wildstar felt boring and uneventful to me. If I don't get hooked after a couple of days, its just not going to happen.
I've played most mmos out there but have only stuck with guild wars and guild wars 2 for any decent length of time. GW2 from start to current. Its got a little boring now but with content being updated all the time it keeps me occupied.
Alloids was quite fun until my 'extra power' ran out and my toon became next to usless unless I paid for another boost.
The only main stream mmo I didn't play was Tera, that's only because I couldn't get it to work.
The Secret World was a lot of fun, but I stopped playing for some reason and it would have taken me too long to learn the ropes again. Its a mmo to really get into and spend a heck of a lot of time building toons.
Neverwinter was another fun one. I even put some real cash into that one.
Nothing will ever beat neverwinter nights pw's, although not a proper mmo, it was by far the best mmo out there. None of this namby pamby crap. When you die in nwn you would end up loosing xp and levels, which you just spent weeks getting. No game have I ever put as much care into a toon as with nwn, you had to know the ins and outs and your capabilities because dying was not an option! I still play it now and again, but its such a pain to get working. Every class had its vital uses and was as important as the next.
