I don’t think Colonel’s Bequest should be remade. I usually end up liking the older versions more since better graphics don’t really make a better game. I would like to see more games with that style of gameplay and those mystery elements where it’s like an interactive Clue game. I like whodunits and the trial and error of solving a mystery.
Infocom made some good mystery games if you ever want to check those out. They’re text adventures. Suspect, Witness, and Deadline all involve solving crimes, and they’re my favorites. Moonmist is another mystery game but I don’t remember much about it except that it may have involved a haunted house. The crime games are more like a cross between Police Quest and Laura Bow, though.
