PS Plus January: 8 Reasons You Must Play Day Of The Tentacle Remastered
7. It Contains Commentary From The Creators
As you start Day of the Tentacle, you can put on the commentary of the creators and listen how every element of the game came into fruition. This was already done in Grim Fandango - developed and remastered by the same team - and worked out perfectly.
Granted, you shouldn't do this on your first playthrough, as you're unable to hear what the characters are saying, but you'll learning something else that makes DotT far more special - how early PC games were created.
Just go to the bonus menu, turn it on and learn some cool stories from the creators about the plot, the animation and the music.
