With no clear ending or fixed path, sandbox games let players create their own goals. Do you play sandbox gamea frequently? What keeps you coming back after you've already done most of what the game offers?
I think sandbox games are easy to come back to because there's always something new to build, explore, or experiment with. Since there isn't a single "right" way to play, they stay interesting even after taking a long break.
I enjoy sandbox games from time to time, but I don't play them all the time. I like the freedom to try new ideas or set my own challenges on sandbox games. .
