the game device (at the start) is like a constant imagery in manhwas it's so stupid they keep pegging that "it's the future of game devices because it's all your senses and you don't even have to move a muscle!! you gotta buy it it's the future bro!!!!!!!!!"
like whattt you KNOW what else doesn't require you to move and triggers your senses either way???? AUTOMATIC ANAL MACHINES IN DOUJINSHIS
for reference these two panels show the stupid game device contraption they call "game capsule"
