Games that strive to accurately capture the real world: believable physics and ballistics, the behavior of machines and people, and the serious consequences of mistakes. These are most often driving, flight, and war simulators, but the label is also found in shooters and survival games, where authenticity is paramount. Be prepared: such games rarely forgive carelessness.
Not necessarily. Realism is, first and foremost, about the world's plausible behavior: physics, ballistics, and consequences. There are realistic simulators with simple visuals and beautiful games that are far removed from reality.
Are they difficult to understand?It depends on the game. Serious simulators require a learning curve, but many offer simplified modes and help. Start with those that feature a tutorial or "arcade" mode in the description.
All realistic games on the site can be downloaded via torrent — sort the list by rating, size, or year of release.
