Why can't you justify a console? The cheapest Xbox is 300 dollars. If the console lasts 5 years, that's similar to paying 5 dollars a month for a streaming service.
If I want to play God of War a few hours a month then paying 700eur to enter or 75eur and a Netflix style subscription? Which is more reasonable sounding if you're not devoting much time.
Put it this way: Why do people use cloud based hosting over buying their hardware?
Mostly it's because they convert the one time cost to an amortised cost based on usage.
And you can also finance that for £20.99/mo for two years.
And you can also re-sell it when you get tired of it.
