My son has hunted he wants a steam deck. I know nothing about them. We don’t game on a PC. Xbox and ps. So I was wondering if I buy this will it work out of the box like an old Gameboy. I know it’s all digital and I would need to get him games but I am wondering if a computer is needed for anything? Or if I can set it up to wifi get him a steam gift card and let him have at it. Any info you have would be great.
