I lean towards multiplayer games because most single player games don’t do it for me. Exceptions are Mount & Blade, and Bejeweled 3, which are both games that I play to think; they keep my active mind engaged enough so I can work out other things in mah brain.
I also play almost exclusively in Steam, to get achievements. I am slightly embarrassed to say that a large part of it is getting badges. I don’t even want all of them, I just want a lot of them. It is a little hit of dopamine that I appreciate.
I actually intend to deconstruct games in a systematic way, so I’ve been collecting games for a while and not playing them, so I can build out the infrastructure for my project. I imagine that the discussion it will create will encourage you to play games in parallel with me.
