Arkane Studios are one of my favourite developers. Playing through Deathloop has made me realize that I’ve been playing their games the wrong way for years.
I’ll get into the nitty-gritty of this revelation, but first I want to frame it within a general game design principle. It’s not enough for designers to provide players with a myriad of interesting gameplay options (as Arkane games certainly do). Within those options, players may find a strategy that’s boring but reliable and effective. The existence of such a degenerate strategy may lead some players to repeatedly use it even if they ruin the game for themselves.
It is therefore essential that designers make boring tactics impossible or ineffective.
