Experience boost events have become quite a regular routine in many MMO games. The instant reward you get from experience boosts are more than enough to get many players to jump back into a game, even if for only a weekend. Many new games may offer double exp when a new server comes out, or during special events, or when a new expansion releases.
So do you like experience boost events? Do they get you to come back to a game that you haven’t played in a while? Do you think they cheapen the game and only bring in players that want the exp and then leave?
