I was reading through this interview again, conducted by Dalixam from World of Monkey Island, and was quite surprised when I came to this question, and even more so when I read the answer:
Some fans would like to see MI1 remade with today's graphic and voices. Is that something you think is a good idea or do you feel it should be left as it is, for nostalgic reasons.
Remaking MI1 would be a huge mistake and wouldn't add anything to the game. Having recently played the game again, it's just fine.
