Every once in a while i get a feeling of nostalgia towards some games that i've played and love dearly because they have taught me something or i've enjoyed them for some specific reason or they are so aesthetically pleasing or maybe the plot was so exciting.. Then i decide to install them again.. (and end up just having them installed on my PC all the time, eh)
I can name a few that i really, really like:
Black Mirror-This point & click adventure has just the right atmosphere and i really enjoyed the story.
Skyrim- ah, Skyrim, we all love it.. i can explore it's forests for hours and never get bored..
Dreamfall- probably my fav game of them all.. story is just.. epic, if any game somewhat changed my life this would be it.
Alice-Madness Returns-So aesthetically pleasing with various amazing levels, interesting story and a touch of spooky scenery.
Gray Matter-which combines elements of scientific and supernatural environment with a touch of gothic, mostly in the appearance of a main female character and architecture, love it!
Scratches-yet another point & click game with a great horror "i'm alone in the spooky mansion" atmosphere.
Still Life-really interesting detective game..
Vampire the Masquerade-Bloodlines, the best vampire game there is!
There are more for sure but i would pick these as the games that i can play over and over again and never get bored.
