SaiNt: Checked my archives, and the earliest post I can find relating specifically to the Remake would be March 11th this year, IIRC.
I'm sure there were ideas getting flung around earlier than that about possibly rewriting things in the game, but that was the earliest topic I found about remakes.
Of course, my archives don't go back to last year ... but since LGP Tools v1.1 only got released Dec/Jan, we can't have seriously discussed a Remake before then ... I think.
