yes the game is worth but keep in mind you cant just get the game and be like the others that was before you day after day in the past. You need some Times to recover what you lost and if you are new you need a bit to farm like crazy but at the end you will come togheter with the rest . Just log in and farm a bit around because sometimes some players have different style of playing so who knows. Never say never . The People are saying no but they still play so ? Is worth? Get in the game and see it . Gameforge destroy the game 50 % with all the bugs ,events and the P2W but 50 % is the players that dont know to share info and to help everyone to have a good start. Is just my opinion with respect to everyone
Mind elaborating what you mean with "farm like crazy"? xD
Farm "like crazy" won't give you any max. Daeva Skills or Stigma on +15, which is the level of most the "rest".
If you fix it to "make aion a full time job with 8h a day on multiple character" and "never miss any event" to maybe/perhaps/eventually catch up to the "rest", then I would agree with that.
In the end it depends on what level you want to catch up. But hell no you won't be able to recover as a beginner to the level needed to compete with other players.
