If you have not played the game for over 2 years, then you will feel as new as the next person who just bought the game. To my knowledge, as far as where being part of the game is concerned at this time, you have no advantage in game if you have not played the game for that long. The early adopters of the game who have been playing since the last wipe will have some vast advantage at this point because they would have accumulated a vast stash of rare resources before they became rare, they have more plots, and more skill points to spend.
But, if you have not been playing since the last wipe, then it will be just like anyone who has just started to play the game. Welcome back though !
