So I’m guessing they’re trying to make an entire world for you to explore, whether you enjoy that or not is going to be up to you and the type of games you look for.

Personally, I was never able to get into the Minecraft types so this probably won’t be for me, but if it’s good I’ll likely still give it a go.
