Ideally I will look for games that will keep me interested for hundreds or potentially thousands of hours such as Path of Exile or modded Minecraft. While I do enjoy a good singleplayer story as well, that sort of stuff is usually something I'll do every couple of years. I enjoy having multiple high time sink games to come back to and and cycle through in periods. Also a big reason why I used to play so many MMORPGs.
I have that plushie! Love it
