There ' s a mode to play where you don ' t have to continually top up oxygen and food . So it ' s not so much about survival more exploration . I think it ' s really good . But I have it and Realms and given a choice I would choose Realms . <| sep |> In regards to the disclosure , I believe that a US federal requirement . I don ' t argue with your points at all . There is probably no legal requirement to include the disclosure in UK or here in Canada for that matter . Nor does Amazon appear to require it . Should you disclose it ? Yes , I think you should . It is information that is relevant to the consumer . If they think that reviews of freebies are tainted , you should let them know yours is a freebie . Even if you think your review is not tainted . It really doesn ' t matter what you think . The only risk with getting banned is if you have Vine . If not and you don ' t think you ever will and you don ' t care about the health of the ecosystem just go ahead . Just know you are part of the problem . I have no faith in any reviews I read on Amazon anyway because I think about 50 % are tainted and another 40 % have no detail .
