Richard of PopCults.com writes "I am going to tell you my feelings about Dungeon Travelers 2: The Royal Library & the Monster Seal right off the bat: it has become my current addiction game of the year. Ever since I started playing the game to review it I have hardly put down my Vita. I play it at home while watching TV, I play it on the train to work, and I play it at work… I have even been playing it in bed on those nights where I can’t sleep (which is probably caused by my wanting to play more of the game); I just can’t seem to stop playing the game. And it isn’t like Dungeon Travelers 2 is any big marvel of a game – though it has a deep evolution of a 'class' system, the game is pretty simple; but I think it is that simplicity that makes it really appealing. I can either play the game for a couple hours at a time (until I have to recharge my Vita again) or in short burst that I can play for minutes at a time. It is a combination of what the game provides that has me really enjoying the game to the fullest."
