When it comes to Xbox Series S or X, the X is only useful if you have a 4k TV/monitor imo. Most game stores only sell new tripleA games these days anyway and there's enough sales and games included in things like Game Pass to keep you satisfied and saving money. The only thing you'd be missing out on is cheap preowned games. It felt weird not having a disc tray at first but it hasn't stopped me playing any games or cost me any more money than having one would've, especially considering the series X costs nearly twice as much as the S.
