Aion is without a shadow of a doubt the best PvP game released in the last 5 years. When I first picked it up on release I was literally BLOWN away by the stunning graphics, personally I liked the grind, it gave the game actual longevity although I do realise it obviously burnt a lot of people out and needed fixing. Sure the graphics are not that amazing compared to some games released since but for 2009 the graphics were absolutely mind blowing.
I only wish I could go back to it now but I can't thanks to how terrible AionEU has been made, so wish I played AionUS .
