The 1990s saw the rise of 3D graphics, which brought a new level of immersion to video games. Games like "Super Mario 64" and "Tomb Raider" were designed to take advantage of 3D graphics, creating new gameplay mechanics and immersive worlds. Game design became more complex, with designers having to consider how the player would interact with a 3D environment.
In the 2000s, online gaming became increasingly popular, leading to new challenges and opportunities for game designers. Multiplayer games like "World of Warcraft" and "Counter-Strike" required designers to create complex systems for matchmaking, chat, and social interaction. Mobile gaming also became more popular, leading to new design challenges around touchscreen interfaces and mobile-specific gameplay mechanics.
