Honestly, I refuse to recognize anything that was made after LSL7: Love for Sail (namely Magna Cum Laude and Box Office Bust) as sequels. They weren't made by Sierra, Al Lowe was barely on board, if at all.
Now, about a remake... There already was a VGA remake, which is still completely playable. Do we really need a "high res" remake with a collector's edition? As fond as I am of the games, as nostalgic I may be of those carefree days when I played the game behind my parents' back, well... I'm not sure I really want to see this series resurrected. Again. The horse is dead, stop beating it; get new ideas, new projects, go in new directions.
