Level-based progression is an extremely popular way of providing the player with the feeling of “getting stronger.” The system is born with Role-Playing Games (RPG), but it is nowadays embedded in practically every game; some more, some less. Even if it is entirely possible to provide progression feeling without levels and experience points, level-based progression is natural, direct, and linear, and it fits well in many (too many?) game genres.

However, not every experience-level progression is the same, and it is essential to design designing a fun system. Many games do that without much thinking: they just slap experience points and level, and that’s it. The general idea is that the more is your level, the more experience you need to advance to the next one. This is true, but it is just a small part of the design. In fact, you must keep in mind the effect of any gameplay element on the player, and you must be sure that what you do produces the emotion you want to convey.

Times ago, I was reading something on numerical systems and password generators and I find myself discovering Diceware, a system for generating a passphrase using several 6-side dice. I think it was funny, so I looked for some dice in my house to try the system. Unfortunately, I have just one d6. Diceware requires five throws just for a single word and a good passphrase requires 3 or 4 words, plus some modifiers here and there. In total, I should throw that single die 20 times to get a good passphrase.
