Good 'short' games?

[KOOKIEZROCKS]

Most of my owned games are ones that need a devotion of time to fully enjoy (Fallout, Skyrim, Borderlands etc). Although I love these, I want to change up my lifestyle abit. When I say short, i mean I want something that you can sorta use to wind down a little, as in I dont have to think too much when playing it but still provides enough of a challenge to feel exciting. Just hop in, enjoy for like a cool 30mins, stop and feel satisfied or relaxed.

Ive thought of stuff like Overwatch?

What do YOU play or what do you think are games that fulfill these more casual times? I prefer multiplayer but im open to any suggestions :)

P.S. I'd rather avoid Mobas like Dota, played League for years and now I hate it.

Thanks in advanced - Kookie

Fallout 1 is actually really short if you know where to go and I suggest Cry Of fear it’s a 8/10 and it’s only a couple hours long

My go-to game for a short match is Killimg Floor 2.
