So this is my honest opinion after quickly pre registering for this game, install and trying out. To put it bluntly, it's gold encrusted crap....great graphics, that will set your phone on fire after some hours, nice, though limited,  customization.  But basic repeated missions of killing 100, 200, to 300 monsters. High high high farming is involved and focused around diamonds. You want anything quickly to advance easier, must buy diamonds and of course it's not great. High price for little amount of diamonds.  I say little cause compared to the price of things in the market,  out rank the price for diamonds.  Basically like spending $10 for a blue gear. Just one. It's big open world, createable characters, nice graphics. But if you're not gonna be a heavy whale p2w player then this game's waters are too deep for you. Nearing 8gb for download its alot of content I believe. But you'll never see it without leaving a money trail every step of the way. If you want to experience it, then by all means go ahead. By day 3 if not sooner, I'm sure you'll  want to unistall as well. This game main downfall to me is its not giving you any gear from completing quest, or any high monster drops. Played for days and got one weapon drop. A normal type...so unless you farm to death all day in dungeons or spend Hella cash daily, I wish you luck in your endeavors
