Supergiant's Pyre ($20 on Steam) has me thinking about repetition.
All games are repetitive, be it on the macro level or micro. Pong, you hit a ball back and forth. Super Mario Bros, you run to the right and sometimes jump. Doom (and basically every shooter since) you enter an area and gun down everything that moves. The Witcher 3 might house one of gaming’s best stories, and some of its most creative side missions, but even there you’ll do an awful lot of “Following the glowing red footprints to the waiting monster.”
