I have been watching a tutorial for a game in blender, but when I open the blend file it automatically starts the game engine, is there a way to bypass this?

Answer 1

Just use the -Y command line switch. To quote from the blender wiki:

-Y or --disable-autoexec 
    Disable automatic python script execution (pydrivers, pyconstraints, pynodes)

Beware! That is an uppercase Y
