I'm on a bit of a F2P MMOG tour.
I dont generally spend money, am fairly impatient and fickle and dont devote more than an hour or so a day to any MMOG. I am a solo MMOGer in that I dont play with friends but always look for and enjoy group PvE events. I dont really enjoy PvP as I am never good enough at it and dont enjoy failing/dying frequently. So far i have tried:
GW2 - OK, it's B2P not F2P but it prompted me to start looking at F2P as I felt I did not get good value from it. Wonderfully conceived world but frustratingly limited combat/magic that made this game simply boring for me.
Planetside 2: Too PvP oriented and i died too quickly and too often to get into it.
DCUO: Lots of fun in the early levels but increasingly felt that i was missing out on or misunderstanding aspects of the game as it rapidly became too difficult so I quit
Star Trek Online: Struggled to get into it, insufficient hand-holding left me lost too often
Neverwinter: Really enjoyed it - loved getting to level cap but then got bored and annoyed with some of its restrictions. So far this is the best I have played.
SWTOR: I really enjoyed my experience getting to Lvl30 before getting bored as the pace slows down so much for non subscribers
Firefall: yes, its a beta but it was the quickest I have installed and uninstalled an MMOG. Got completely lost due to the almost complete lack of a useful tutorial and hand-holding.
Rift: my current game but one I am really struggling to enjoy as I dont really understand what I am doing/supposed to be doing and am pretty lost. I will persevere for a little longer but expect this to be a short-lived experience.
From this i would conclude that I enjoy MMOGs that are easy to get into, easy and fun to play and don't bombard you with depth and complexity at the outset but open up these possibilities as you reach higher levels.
I know I am a hard to please gamer and am expecting some sarcastic comments but my question is what F2P (or possibly B2P) MMOG would you recommend i try next?
