I don't have a steady group anymore so I bought this as something to play when I wanted to Role Play. I didn't know what to expect and I was happily surprised.
PRO: The game is fun, it is Role Playing by yourself, your character slays monsters or faces challenges and in return earns loot and upgrades, the game can be challenging (I myself died a few times), you can start playing within about 10 minutes, the system is so easy that you can start playing quickly and later down the road you could probably write your own quests or monsters without worrying about balancing issues, IT'S ONLY $2.
CON: You do have to flip back and forth to certain pages. If you are using the pdf, then bookmark the pages.
I have already suggested Dungeons to all my friends and I suggest that you get your copy as well.
