39 here. over the years gotten bored with action games, and even films, i prefer something which requires a bit more thought/imagination.
Soma is excellent, love the use of sound in this game, and its pacing is great.
FSX. always a challenge, learning how to use GPS/navigation trying to perfect your landings etc.
Alien Isolation. love stealth games in general, and survival horror is my fav genre, i know it comes under action, but you don't have to go that route.
Arma 3 , just installed it , not give it much time, but i can see it will require a lot of patience and thought learning how to navigate with a map and compass around large areas, planning the best route etc.
Portal 2. great game as like its predecessor, first person puzzle solving set at your own pace.
S.T.A.L.K.E.R. it's been one of my fav games since SOC. i love its dystopic bleak world with strange events and thick atmosphere.
