I know it's corny, but my favorite part is right here in the forums, discussing the game and strategies with the community
In the actual game, I love that thrill you get when you realize you've just bred the dragon you were trying for. Unfortunately, that hasn't happened much for me lately While I appreciate the sale prices on new dragons being really low lately, it's kind of a buzz **** to buy an egg instead of accomplishing it by breeding IMHO.
I also really, really enjoy the Tales events. However, I probably wouldn't even try to do one if I couldn't come here to read the steps ahead of time. Love all my DS buddies!
