Graphics imo. Gameplay comes next. All games and their gameplay become repetitive and dull at some point. So if games want to hold up to real standards they need to look pretty. Sorry but no one wants to play minecraft with its outdated "stylistic" 8 bit graphic look. Would've been so much better if it had real graphics.
I agree im all about new tech i dont wanna play a game in this day and age that looks like something i already played years ago if so i would just stick to playing old games and dont waste my money on new games
