I will say this.
I see less people "complaining". I don't know if this is because they gave up, or the Aeria team might actually be doing something. Recently, GM activity was re-introduced to Grand Fantasia after about a year and a half of nearly no events, or even seeing a GM.
But, with every other one of Aeria's games...I'm not entirely sure. I have played Grand Fantasia, Eden Eternal (horrid GS's there except for when Amigo was on the team, Spongeycashew seems good though.)DWO, DKO, Shaiya, and Last Chaos.
I had heard from a friend that Last Chaos and Shaiya was bad. Now, me being a newbie at the time, I wasn't exactly observant, but I did notice a number of players complaining of horrible communication.
What I have to say to Aeria, your first step is to FIX YOUR COMMUNICATION WITH YOUR PLAYERS ALL AROUND.I'd be stupidly biased if I said Aeria was doing better because some GM's are actually doing their jobs. But at the moment, you have to fix your company all around. Not just your newer shiny games.
