Let's just quote our friends at Birth. Movies. Death. on this one:
"If you've got a PlayStation 4, a PlayStation Plus account and you have exceptionally good taste in video games, you need to be aware that LucasArts' classic adventure game, Day Of The Tentacle, will be free to own during the month of January, starting on Tuesday."
Well, if BMD says so, though they accidentally forgot to mention it also was Mojo's Game of the Year in 2016.
Look down in the comments and you will see one Jake Rodkin trolling around, decrying Grim and poo-poo-ing the new Full Throttle trailer.
Oh, and if you own a 360, Mojo Game of the Year… what, 2013?… is free for Gold members. That's The Cave.
