At the risk of sounding totally casual : Games where I can explore interesting areas. If I can do it while feeling really powerful then even better. Horizon Zero Dawn comes to mind. Skyrim, World of Warcraft, Red Dead Redemption, etc.
Oh, I like playing computer games, I was great fan of them in my teenage years and I still play them time till time, however now that happens not too often because adult life is much busier :p My the most favourite one is Half Life 2, in my opinion it's the best games which had been ever made. I played it so many times…
