I'm new to DQ and I just played my first game today. What a truly fun game!
I really enjoyed it. My GF and I played two Heroes each.
One of my Heroes was late getting to the treasure chamber (about 25% of turns left) and was desperate to get some loot! After waking the dragon once I left/escaped the chamger with plans to return to a reshuffled deck but was sadly killed by my unstable potion.
My other Hero had a good amount of loot. Not enough to win but she was the first (and with a good lead) on her way out. I was hoping the others wouldn't make it out in time... With no clear route out she entered the catacombs tripped a trap (explosion) and died.
My girlfriend's Heroes racked up around $4k and 5k in loot and both made it out of the dungeon. She enjoyed the game.
I did notice that even though combat was mechanically fine it didn't seem to fit the rest of the game. It really slowed things down. I'll likely stick with the combat but I'll also try out FFG's combat alternative.
Very fun game!
