Press Any Key to continue...

I press the key/button it tells me to press usually... but if it says any id probably pick enter

Left mouse-button is what I try first. After that, probably enter

From my experience it mostly happens to console games and\or ports with the gamepad, sometimes 'start' or 'X' or 'A' can be specified. It's interesting to see how people use their freedom of choice.

Haha sometimes like even when it specifies a key or button another key or button can still start the game which makes no sense to me either way if it tells me to press start I press start if it tells me to press space I press space... I dont want to get into bad habits and then be surprised when a game doesnt start when I push a different button someone some day will make a game where if you do as youre told and push the right button youll have access to the game and if you press something different to start the game you might end up with something changed or some kind of reference that you couldnt follow simple instructions

Spacebar- typically the largest key on most keyboards and also the one that doesn't usually break anything if pressed at the wrong time.

Always Enter
