A. Play it fast as if you would real doom, And have it as an action game
B. Play it slowly and think about it - Stratergy game
The best thing about the roguelikes that these two not exclusive. You can play is as fast as you want. Make the keyboard burn when things go easy and sit back and think hard when though things appear.
*Anyone ever notice how in RPG's there is no role playing?
RPG in computer games mean using game mechanics similar to these in table-top RPG. Roll Playing Game would be a more accurate description of the acronym.
To add to a content my previous post:
Roguelikes are neither action, nor RPG games. They form a genre of their own, although, they have some similarities in play mechanics and share common roots with CRPGs.
Inventory management is an integral part of many roguelike games.
