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?
Source engine is just so clean looking that the graphics can hold up, the geometry is all crisp and clean but lighting effects hadn't really developed beyond bloom at that point. Almost like minimalist graphics, in some ways I even prefer that. The game feels so light and free and all the art design is perfect for it.
