Comment MUDs are text-based MMOG's (Score 1) 149
Most MUDs are also CRPG's with levels, equipment, quests/missions, et cetera. Little to no puzzle solving necessary. Thus they share more in common with World of Warcraft than they do with adventure games.
Survival horror games (e.g., Resident Evil, Silent Hill, et cetera) even though they have a lot of first person or third person shooter characteristics actually have more in common with adventure games because of the perpetual "find key to open door and advance storyline" situation.
