This makes a lot of sense; not many people make games that accurately model reality (with a few notable exceptions) because, quite frankly, video games are supposed to be escapist. Most gamers spend quite enough time dealing with reality without dealing with it during relaxation/fantasy time too, especially if it makes the game a lot harder to play.

Besides, having your game accurately model reality tends to make you look uncreative (and usually like a bad game designer, as mentioned above), which cuts into sales. Games are a business, after all!
