I absolutely adore all Portal games, have 100% in each of the official games as well as mods, have done Portal Stories: VR as well, would love to see this as an addition to the game. It seems this has been brought up several times in the past, and appeared to have been considered at one point; regardless, would love to see them, would attract more players again, and would make for some more replayability within the game. Love the game, played it like 3 times, great stuff.
