Those very "palace ruins" were made with the help of 3DO and NWC themselves.
A game still selling after 7 years is Starcraft, and in much larger volumes.
DMM&M already wrote in the thread dedicated to it, but I'll write here as well. Why on earth did you decide that this was a sequel to M&M??? Ubi said right away that they were making an action game (a sequel to Crusader of M&M and Legend of M&M); there is no need to attack them just because you expected something else, without bothering to read the announcements.
