Never occurred to me to play a board game solo as a kid either, and I used to bring my NES controller and a Super Mario Brothers 3 Strategy Guide full of maps to my grandmother's to pretend to play through the game.

But I design board games now, and boy do I ever play my own games against myself now. I'll play up to 4 players solo for playtesting purposes, no problem. So far the only types of games that it's seemed pretty impossible to do this with are social deduction and party games.
