Yes I recommend you to do so, because the original version Gacha Club game for PC can't play games only for Android, For PC is only for creating characters. But the Gacha Cute which is the upgraded one Gacha Club the games are playable for PC users and it works perfectly well, If you download it and it can't be open if you did not download this app: https://www.win-rar.com/start.html?&L=0 you will have to do so. But it is your option on you should download this application to waste your 178 MB, This is my advice for people asking me by recommending, I did not dare to tell them to do so because of my opinion, many people has their own right to make their own choice. This is my recommendation of people asking for my opinion, Thank you for reading :)
