What's that one adventure game you can just boot up and have a great chill time with? Mine would probably be Day of the Tentacle. It's such a wonderful, colorful world to inhabit, and all the characters are lively and oozing with personality (no Sludge-o-Matic pun intended). I could spend hours just walking around talking to characters and not even think about solving any puzzles.
What's the one game you'd boot up to just relax with?
Probably the Quest for Glory series for me. Played them so many times that I can just pick up any one them with any character and get sucked right back in to the game. I've had an itch lately to do a full playthrough of all 5 games after not touching them for a long time but I have little free time and too much backlog...
