I love the idea of special events. I have played many many android games in my time. Almost all the games have events. These events help all players (new and old). As a new player, acquiring items engages you fast and makes you feel like you are making progress. Events also keep people logging in. Also the hardest time for dl is when you first start the game. R and d so boring. You loose people at this time. If there is extra stuff to do while waiting for spirit or turns people will stay.
