Minecraft, while nothing particularly special to me, is most likely what I would choose. The potential for making your own fun in that game is ridiculous even if its been the victim of bad new mechanics bloating vanilla for the past decade. Even the longest of my favorite games cap out around 200-300 hours with all their content squeezed out of them, and with the amount of gaming I do on the regular thats gonna last me a few months at best.
Why is "fucking" censored???
