This game has been out for some time. The more you play and the longer you play the more perks for your dragon and you. That part is good.
There is a single player, co-op and pvp. There are only 3 maps so single player gets dull quick. Co-op allows you to play with other players on your team but the AI is relatively weak so they get steam rolled pretty quick. The only real joy would appear to be pvp. The matching system in pvp however makes it so as a new player you might be playing against very high level dragons. You will be killed easily and quickly by them, often. As such, while you may occasionally have a good game in pvp. Largely you will be used by high levels to bolster their kill ratios.
There also appears to be a fair amount of hacking going on that seems to be unchecked. All in all, it appears like a very fun game but as a new player don't expect easy or enjoyable, you will be a wonderful target.
