Playerunkown's Battlegrounds has a great vibe and is fun to play. However their are some stabalization issues that are currently being worked on by the developers. A must play with friends at the time of writing.

Great game for 15 euros. Graphics are top notch for the time.
Dark Souls-esque game which is sometimes even harder than it, at least when on normal or hard difficulty.
If you like Dark Souls, this is worth it. And it's only 5 euros now...
