Are solved games worth playing?
Here are 3 reasons why I sometimes play solved games:


For the benefit of the other player. I play connect 4 with my 4 year old nephew. The point of the game for me is the bonding part. For him, its bonding, thinking ahead, playing to win and the tactile feedback of playing with the pieces
To find the solution independently. I was introduced to Nim in a mathematics lecture, where the problem was to solve the game and prove the solution works. The point of the 'game' in this context is not to play it at all, but to have a concrete subject matter to apply abstract reasoning to
To add more complexity later. Tic-Tac-Toe on a 3x3 grid is solved, but I'll introduce the 3x3 grid to new players before going to larger grids
