Less "grit" more fun. So many games obsessed with "dark", "gritty" and "grim" and forget to also put the "fun" and "interesting" in.
More gameplay, less space to spread it out in (looking at you Open World Ubisoft Games).
More games that finish, that have an ending, a story that has a satisfying completion. No more of this "It never really ends, you can keep grinding forever, see what's new in the next season pass, etc etc" rubbish. (basically, less GaaS)
More simple games. Not everything a big publisher puts out has to be a massive open world cinematic blockbuster. Wouldn't it be nice to have a "Triple-A" twin-stick shooter or something every so often? Pretty sure they must be significantly cheaper to produce.
Less "online play" in my "single player" experiences.
