What would be the most popular chess opening lines, IF castling was not allowed?

So assume we were playing regular chess, but we only add a small variation: no castling; how would you open the game?


Opening the center means exposing your king, closing the center my give the king trouble as strong pieces of your opponent can give you a lot of trouble!


Without castling I would open on the flanks, and develop my rooks, early on the game (b4 or g4)





By the way, could you please indicate a notable game in which one player castles and the other does not yet ends up winning the game!|||King's Gambit and the Vienna Game would be more popular for white.

In some variations, white does not castle, yet gets a good game.

There is less of a drawback if white cannot castle anyway.
