Every time I start playing Factorio it's always a matter of time before I'm trying to figure out how to solve factories with VHDL and how to interface Magic VLSI with the game's blueprints. From there it's another day or so before I'm reviewing EE graduate programs and working out how much math I would need to grind.

I had this experience with Eve Online back in the day. The optimization limit horseshoes back into the real world.

Case in point: just reading this thread started me learning about discrete event simulation. Damn you Factorio.
