i gave it a 2 star instead of a 5 star because there needs to be clans, a chat system, a trading system, a friending system where we can look up for people names, more ways to get crystals, and way more story missions. Please make these happen and i will change it to a 5 star please. Edit: 3 Years Later and I still feel like getting chrono crystals is hard if you are a f2player...
