syltefar.com: FIUR

FIUR is a metagame classification, common in pay-to-win-style arcade games.

Progression:

 * F: Finishable (has a well-defined ending)

 * E: Endless (can be played forever, barring kill screens)


Continue type:

 - savepoint = checkpoint

 - Omitted if permadeath

 * C: Checkpointed (dev defined checkpoints)

 * M: manual save (user defined checkpoints)

 * I: Immediate (retain current game state)

Continue supply:

 - lives = continues

 * U: Unlimited continues

 * L: Limited continues

 * P: Permadeath = no continues

Resource change:

 - If omitted, no resource gain or loss (games without power-ups)

 - Hit points are normally not considered metagame resources, and

   are expected to be reset on continue, or reverted 

 * R: Reset (reset resources to starting state)

 * D: Decrease (resources decreased, e.g. level down, dropped souls)

 * S: Save-relative (revert to manual save/checkpoint state)

 * K: Keep (no resource loss)
