Dungeon World is one of the more popular games in the Powered by the Apocalypse system. It's a game that is incredibly easy to set up, which is great for new players or ones who want to play in one-off sessions. That said, it is a game that should only be played by those who have a good understanding of how tabletop roleplaying works.
Players start by making characters using a very streamlined process. They assign values to their six core attributes and pick from a handful of class abilities. They also choose a race and alignment. There aren't too many options for each race and alignment, though. For example, bards can only be elves or humans and druids can't be evil.
After that, the dungeon master will give them an adventure. This could be an encounter or a quest that needs to be completed in order to advance the story. The GM will describe the action and have the players make skill checks to see if they succeed or fail. The game is based around keeping the story moving, and this is something that it does very well.
A few things to keep in mind about the rules are that it can be a bit complex and sometimes difficult for players to read. Especially since the book doesn't use great fonts and colors to differentiate major sections. There are also a few clunky mechanics that make it difficult to understand what is going on at times. For instance, the player gets XP for each roll they make even when it's not successful. This can cause players to attempt rolls that aren't tactically wise and may end up disappointing them.
