While I still can't play Aion, I may as well give my impressions of it up to this point. Don't worry, it is not too colored by my current predicament ;) I've actually played through the first part of the game twice, due to the server move. The good news is the second time goes much quicker.
Let's start with the positive side. It sure does feel polished. Is that like saying someone has a lot of personality? The graphics are good and combat is very smooth. It feels like it has been released for a year already.... which is has. That about covers the positive.
On to what makes Aion meh to me. The gameplay is very derivative. Seriously, this is the same game we've been playing for years. I find it completely uninspired. That's ok though, as I'm not playing Aion for the PvE.
I must be a glutton for punishment to put myself through 25 levels of this just to get to the Abyss. The wings are a neat touch, although a jetpack would be better. It would also be nice to be able to use them more.
I should be able to play again tonight, but I have my doubts. Some issue will arise which will prevent it from happening.
