Go watch a stream of GW 2 - So happy I didn't pre order, the fact you had to pre order to get into open beta kind of screamed negative things anyways. People are quite bitter about it.
Tera isn't free to play if there is anyone actually wondering. As to them making loads of money from it, yes they are. Pre orders alone on Amazon passed diablo 3 and gw2 for both collectors edition and regular copies. Everyone even got to play open beta without purchasing first unlike gw2 and the sales indicate something more then another wow clone.
Seriously go watch a video Sam, I downloaded it for the free open beta with no intentions of ever buying it. Like you I figured another Aion Korean grind fest. Besides the generic quests that every MMO has to help guide you through leveling areas it is no wow clone and the combat system makes it actually fun to level not just an obstacle to end game and pvp.
