It depends on how the F2P model is set up. If it is the most popular ones (microtransactions) Then yes, pretty much every mmo that went F2P and added in Microtransactions saw HUGE increses in subs, and subsequently more money spent.

Think of it this way. If you can get everything at a set price of $15 a month with no extra fees as a developer. Sure thats a good thing depending on how many people you have actually paying. Everyone else is shut out of the game

However if you have a F2P model, ANYONE can come play the game, and therefore get sucked into it, and EASILY pay more then $15 on in game items via microtransactions. Which is the main reason i very much dislike microtransaction MMO's.

I have played one or two here and there, but there never anything i get attached to as i dont want to start spending tons of money on usless items i could and should be getting for free. I know developers like AreaNet and PerfectWorld entertainment make stupid amounts of money on the free to play model.

Now a game like WoW or FF going with this model more then likely wouldnt be a good idea IMO, as the amount of people who would prefer a flat monthly fee (like myself) tend to stick with these games, and would much prefer to keep it that way. Since most games tend to lock you out of things unless you otherwise pay for it via said microtransactions.

Soon with lvl 80 as Shadowbringers (3rd expansion pack) will be in the free trial.

Hell no! Let that garbage DMC game die.
