Well, it's difficult to tell who legitimately guessed yesterday's Remember This and who did because google searching appeared to be rampant.
I'll just say that the game was Anno 1606 and leave it there. I was sort of running on the honour system here, but maybe I can't do that anymore. Shame. Even if readers are being honest and using the spoiler tags, it's still ruining the fun. Considering going back to ScribbleTaku for a while to sort of weed it out.
