Simple Loading is the most common type of loading in video games. With Simple Loading, there's very few moving parts on the screen. There's often just enough to tell you if the game's frozen but sometimes it doesn't even tell you that. This type of loading uses art and/or gameplay tips to keep you engaged long enough so you won't notice that you've been sitting there for a few minutes now.
Animated loading takes simple loading to the next level (literally!). Animated loading screens sacrifice a bit of load time for style. They usually give flavor to the world and keep the player engaged with fancy art. Animated loading screens are not separate from simple loading screens and usually have similar elements. Loading bars, spinners, gameplay tips, lore facts, and stuff like that.
Hidden loading takes a loading screen and twists it a bit so the player might not even know it happened. Sometimes this is done through asynchronous loading while you're walking down a long corridor or riding an elevator. Other times developers like to hide the loading behind cinematics. Either way, the goal of Hidden Loading is to keep the player immersed in the game.
Input Loading is kind of like hidden loading except while hidden loading tries to keep you immersed, input loading tries to keep you engaged. They're not afraid to take you to a new screen as long as you don't quit the game. Due to a copyright law on "Loading Screen Minigames", there's not a whole lot of loading screens like these on the market. The copyright ended in 2005 so maybe in the future we'll see more input loading screens.
Here are some key take-aways from this small exploration on Loading Screens:
