I wouldnt recommend taking in our opinion, whose opinion you should get is the audience for Tomodachi life. As we arent your target demographic, or at least most of us arent, its best to ask the people who are.
If it helps you decide some, I believe that games on roblox related to or inspired by other games usually blow up some with the release of the game it was related to or inspired by.
For instance jailbreak will probably get a lot more players if or when GTA 6 releases.
