Ended up getting Rocket League, Day of Infamy, Wolfenstein: The New Order and Goat Simulator in addition to Mafia 3 and Planet Coaster. Decided against Fallout 4 in the end, I just don't think I'll play it after a couple of hours because that's pretty much as far as I could be bothered to go in Fallout 3 - maybe I'm just weird.
Had a go on Mafia 3 for a few hours this morning and I've been happy with it so far (love the music as well) just a shame I'm not able to play it (or the other games) until next Saturday now.
