Come on man I could build you a custom made PC right now that will play every game just fine on medium to high settings for 700-800$. Windows can be downloaded easily from any MSDN friend, just go to your friends and ask for a copy of one of the various windows licenses he/she gets from the University or buy a OEM license. Besides you dont need to pay 200$ on HDD/SDD that’s something you invest in further down the road, just buy a 60$ 500gb hdd as a start
I am thinking it will be like 360, if you have a game installed on the 360 via your account and then want to let your brother/sister/son or whatever play it it would just function normally. The Xbox already knows it’s installed on your Xbox for a reason – you bought the disc and installed it – which means there is no additional verification. But if you bring the Disc to Another Xbox and account you will get troubles
Or store your account and game on the external harddrive that you may buy and bring that with you when you are coming over to your friend’s house.
I mean if you are complaining about the 500gb space I would guess that you are going to buy a bigger External one – if that works as I Think it will – and there you store the game and your account how hard could it be
