I picked up "Mafia: Definitive Edition" cheap the other day (I've linked it on Steam as it's still on sale for the next few days).
I was a fan of Mafia (the original from 2002) and felt it was cheap enough to give it a shot and I'm glad I did: besides the infamous/arduous racing level I found it to be very enjoyable overall.
I was sad to see that there wasn't any "Freeride Extreme" in the latest version (this was bonus, fun, ludicrous content, available after completing the game) as it would have been a nice addition, the "Freeride" mode is likewise a little lackluster but the actual campaign is great.
What was the last game you finished? Was it any good?
Pretty sure the last game I fully completed, not just did a successful run of, would have to be Beyond The Edge of Owlsgarde.
It's a point and click adventure game where you play as a deer who comes home for some sort of celebration, only to find his parents are missing. It's charming enough and I found the cast to be enjoyable, especially one special death scene where the English voice actor for the main character improvised and created a hilarious scene because of it.
It's short enough that a full non-commentary playthrough is around 2hrs20min long, but I definitely spent a lot longer on it since I had no idea what to do in certain scenarios. If you don't mind anthro animal characters and are looking for a decent modern point and click, I would recommend it. I personally enjoyed it despite sometimes having no clue what to do.
