This is true, but through the 80s and 90s (excluding the last few years discussed above) there were very few big games from these franchises either. Battletech had its most successful game in Mechwarrior 2, but this wasnt really huge. Star Wars fared a the best with a few reasonable hits - Tie Fighter, X wing vs., Dark Forces and Jedi Knight, but none of these were really anything approaching the scale of Warcraft 2. D&D released games all the time but few of them were better than mediocre (Eye of the Beholder was probably the biggest). Warhammer had nothing either.
