In recent decades, the development of new technologies and advanced innovations in the field of video games have taken the gaming experience to a new level of reality and sharing. One of these technologies is Augmented Reality (AR), which has brought significant changes, especially in the modern gaming city.

Part I: Augmented reality concept Augmented reality is a technology that combines virtual information with the real world. This allows games to offer users a transformative experience that benefits from digital elements in addition to the real world.

Part II: Effects of Augmented Reality in the City of Modern Games

1. Interaction with the environment: Augmented reality allows games to enhance interaction with the physical environment of the city. Players can interact with the real world around them and complete tasks or game challenges in different locations of the city.
2. Social experience: Using this technology, players can directly interact with each other and combine unique social experiences in the virtual world with reality.
3. Enhancing the gaming experience: Augmented reality allows games to bring story and gameplay to a new level of depth and variety. Players can search for different items in the real world and realize fascinating experiences.

Part 3: Challenges and the future of augmented reality in the city of modern games

1. Challenges: With the introduction of augmented reality into games, technical and social challenges have also arisen. Among these challenges, we can mention the protection of the rights of opponents, the security of personal information, and the balance between the real and virtual worlds.
2. The future: As technology advances, it is expected that augmented reality will expand into more and more games. These developments may lead to the arrival of a new generation of games that bring a broader experience and more challenges, allowing players to actively participate in the game world.

Augmented reality (AR) has given rise to various kinds of experiences in the modern gaming city. Below are some types of augmented reality in urban games:

1. Urban Augmented Reality (Urban AR): In this type, AR technology allows players to move in the real urban environment and combine it with digital elements. For example, players can participate in hidden object searches in the streets, towns, or even historical sites of the city.

2. Social AR: This type of augmented reality allows players to interact with each other. They can meet other players in real places, play challenges and games together, and experience engaging social experiences.

3. Location-Based AR: This type of AR uses GPS and location data to determine the location of players. Players can search for specific points in the real environment and enjoy special digital experiences there.

4. Wide augmented reality (Wide AR): This type of augmented reality refers to games that use a much wider range than the players' normal physical environment. This may include using large open spaces, such as parks or mountainous areas, to create more expansive and natural experiences.

5. Mixed Reality AR: This type of AR combines elements of virtual reality with the real world in such a way that the difference between them is greatly reduced. It allows players to become completely part of the digital world.

Conclusion: Augmented reality in the city of modern games has moved the gaming experience to a new level of reality and interaction. This technology not only allows players to interact with the real world, but also creates new social and interactive experiences. According to the growing developments in this field, the future of video games with augmented reality will be full of excitement and innovation. The use of these types of augmented reality in the modern game city will create unique and attractive experiences for players and help the development. And the progress of this industry has given an important contribution.
