You could use the normal flatscreen monitor as a “ingame” desktop with a few apps on it like “flappy turd” and “Super Lucario brothers”… But if you wan’t to be total 80— You could buy the old monitors… these monitors have a 100% ascii graphics like the old “dwarven fortress” game. This would add alot more fun and immersion to the game. (also ASCII and lazergame goes hand in hand with a bit of vaporwave)
