Undertale is the game I want to experience for the first time again. Can't believe that game is already 8 years old. The music is brilliant. The characters are all compelling. The storytelling is stellar. The graphics.....they get the job done lol
Napstablook was great. Especially once you find out who his neighbor was and a bit more about why he's so depressed. I lied on the floor with him for a solid 20 minutes on my first playthrough. Probably one of the best minor characters ever.
ETA (four hours later lol): The Bioshock trilogy as well. Booker and Elizabeth are imo the best duo ever. Plus the twist in Infinite is a special kind of mind fuck.
