In the 12 months after it came out (whenever it was, 2018?) I only played Forza Horizon 4. I didn't really mean to, but it was a lot of fun, easy to pick up, relaxing and there was so much to do. And I love cars. FH5 will be eclipsed by the fact that my first child is due two weeks after, I'm hoping it'll run on a Steam Deck so I can play it at work but I can't see it being the only game I play if that's going to be how I play games for a while.
I played Red Dead Redemption 2 between April and June and I reckon that if I'd taken it even slower I could've made it last a year. I spent the first few weeks taking it really, really slowly and just enjoyed the lockdown escapism, but then I remembered I bought it primarily so I could play it before the baby arrives and thought I might not actually make it if I kept taking my time over everything, so I started to focus on doing the story missions instead. I think if I'd known how it ended (broadly speaking), I would've spent even more time on it.
