Early Access is the trade name given by Valve, on its Steam digital distribution platform, to games that are not finished. They are still being developed by their creators. That is to say that if you buy this game in an “Early Access” state, it may be that it lacks many promised functions, that there are very many bugs, or problems. By buying a game in Early Access, you take the risk of buying a game not finished by the developers in exchange for the opportunity to see what stage it is at.
We do not recommend that parents buy a game in this state.
