Further Classification: Game difficulty levels

Further classification seems to be an ongoing series about how I mentally, digitally, and physically organize games. In this installment, I just list some game difficulties.

Casual

Games that require litttle-to-no pre-knowledge of gameplay, easily played by new gamers and old gamers.
Examples: Bejeweled, Peggle, Super Mario Bros, I Spy: Haunted Mansion, Animal Crossing
Easily Paired With: Hidden object games, Puzzles, Adventure Games, "Secret Box"

Common/Regular

Games that will be difficult to play if you don't play often, but become a lot easier once you get into them.

Examples: Halo, Call of Duty, Pokemon

Easily Paired With: Most simple genres

Hardcore

Games that require knowledge of the genre or a long history of playing games to be good at. Very hard to newcomers. Interesting to note that some Common games can have Hardcore presences when played online, much like how you can play Chess on a casual or master level.

Examples: Resident Evil 5, Borderlands 2

Easily Paired With: Most complex genres

Master

Games that require a lot of time to be good at. Even if you're used to playing hardcore games, you will need much time and patience to be good at this.

Examples: Nethack, The Binding of Isaac, Civillization 5

Easily Paired With: Strategy games, Roguelikes, Simulations

Cruelcore

Games that at first appearance look hardcore, but soon prove themselves to be comparable to Master-difficulty games. Of importance is that failure here is expected, and often encouraged. It does not simply take time and luck to get good at; you require an insane amount of skill, and may simply be the wrong person to play this game.

Examples: Super Meat Boy, Dark Souls, Marvel vs. Capcom 3, I Wanna Be The Guy

Easily Paired With: Platformers, Fighters
