You’re free to spend your money however you wish, but buying a whole bundle and being OK with not being able to play any game in it? If you would wait for the 10 years until it actually becomes playable you’ll probably be able to get it for even less than $20.
You do you, but I personally don’t advise people buy something until it’s actually working. “Sit on this for 10 years and maybe then you’ll get what you paid for” is bad advice.
