What do you think the game you have played the most throughout your life is? I personally think mine is like 200+ days on all the pokemons combined loool. Or like 70 days on Modern Warfare 2. Game was good af.
Definitely Stronghold:Crusader. I remember playing it every single day for hours and hours as a kid. It came to a point where I'd used a piece of graph paper to get each of the AI's base styles down perfectly and then memorized them.
