Players would use the keyboard, using one keypress to enter a command.
With modern computer systems, users developed alternate means of displaying the game, such as graphical tilesets and Isometric-based graphical front ends, as well as interfaces that took advantage of keyboard and mouse UI controls.
Deriving from the concepts of tabletop role-playing games such as Dungeons & Dragons, nearly all roguelikes give the player control of a character, which they may customize by selecting a class, race, and gender, and adjusting attributes points and skills.
At the start of the game, the character is placed at the top-most level of a dungeon, with basic equipment such as a simple weapon, armor, torches, and food.
Following along the role-playing concept of a dungeon crawl, the player moves the character through the dungeon, collecting treasure which can include new weapons, armors, magical devices, potions, scrolls, food, and in-game money, while having to fight monsters that roam the dungeon.
