at first launch, the game had awfully laggy servers and pretty bad bugs and issues, but recently I reinstalled the game and to my surprise, most if not all of the bugs that plagued my gameplay were resolved, no matter how hard I looked I didn't find any bugs that were detrimental to gameplay. I also found that the servers were less laggy and had some very nice people on them. So I believe that this game was fixed as of recent, they also added the buyable content, although it isn't for me. I believe that it is very worth and gives good perks, like your own personal world and many atoms so you can deck out your base with cool, custom items.
