It has the option of crafting which can give hours of fun if they use that feature properly we can get very engaged. That Diablo approach where you play on a harder difficulty you get more chance to get better stuff is also a system that can get us very engaged. Who knows maybe we will have paragon levels. I just hope that they stay transparent and that they handle their game in a clever way. Hopefully Bungie takes a more pro consumer approach and starts managing Destiny better because selling overpriced DLC or pass or content withouth telling what exactly is that is not a good business practice.
