So I just discovered that Microsoft offer a PC version of Xbox Live Game Pass for PC. Right now it's £1 for the first month and £3.99 per month after that, at least for now.
Considering there's a reasonable library of games available for download and play for that price, I thought I'd mention it here. There might be a few who find it a decent option to play some games at low cost.

If you do sign up it's a little bit of a pain scrolling down to change the region to UK. Keep an eye on it because I found it had a habit of redirecting me to the US site, and I didn't want to risk signing up with the wrong region. Maybe it works, but I didn't want to risk it.
