The question Can I play D&D4E solo? seems to really need an answer recommending Wizards of the Coast's line of Dungeons & Dragons Board Games (e.g. Legend of Drizzt, Wrath of Ashardalon), and a Comment was made suggesting exactly that. That Comment's gone now but I don't know if that's because the Comment should've been an answer or because the Comment suggested a board game or because comments are transitory.
That leads to this: When making a game recommendation, is an answer on topic if it recommends a game from a medium other than tabletop role-playing games?
As a fictional example, were a question to ask...
I want a game that simulates duels between powerful wizards. Wizards have a limited number of spells they cast but which spells they can cast during combat are determined randomly, and uncast spells are saved for later casting. Further, such a game should involve summoning a wide variety of creatures that can be sent to attack an opposing wizards. I'd really like the game to have a detailed resource management system, and I'd like combat to become more spectacular the longer an engagement lasts because of spells that have been previously cast and remain in effect. What game would you recommend?
...would an answer remain on topic if it recommended Magic: The Gathering?
