I USED to consider myself an MMO gamer. Played UO for almost 6 years. Then moved to EQ. I thought, wow, this isn't nearly as feature-filled as UO, but hey, 3D GRAPHICS! Played that for 4 years. Then I started playing DAOC, and a whole host of others, including WoW and even some more recent ones like LOTRO and SWTOR. Each successive game I played lost my interest more quickly than the last. I tried to play ArcheAge and I lasted a whole week before I gave up on it.
Most MMO's have turned into nothing but F2P grind-fests. They are time and money sinks. Either waste a whole crapload of time grinding a quest for a shiny bauble, or, OR... you could purchase the bobble on our store. Not with game money silly, with real money!
I'm still convinced that UO is the most feature-complete MMO created to date, and aside from it's antiquated graphics and interface (Which they may have updated since then) nothing since then has come close.
Now, I play games other than MMO's, but I wouldn't consider myself a fan of any particular genre or style. I do despise most of the mobile F2P games. I don't view them as games at all, they're formulaic, addictive and only designed to get you to spend small amounts of cash frequently so you don't realize that over the last 3 months, you've dumped more into this "free" app than you spend on WoW over the course of a year. Scams are what I consider them.
Sorry if this sounds like a "Back in MY day" rant, but I am getting a bit long in the tooth.
