Thanks
I haven't completed any of the triple quests yet. Or VGT
I tried the 1st triple quest as soon as I had 3000 gold for the building in a quite low unlock kingdom. I got all the way to the 3rd random curse of Mance which screwed me over. I had no experience in Vicious dungeons before, so encountering random non-described gimmicks was new to me. My unexpected defeat made me look for DD related forums to see how others reacted to Mance's tricks. And also led me to join this forum.
I tried VGT right after beating the regular one. Since I didn't know the exact rule for making the subdungeons appear I wasted all my popcorn and blackspace on the main floor. This caused me to lose around the 5th sub, but I didn't know what I did wrong so all I knew I was playing badly.
I haven't tried any of them since, cause I wanted to forget most of the info I've seen about them on the forums, so when I play them again my experience will be as pure as possible. Also I'd like to win by my own skills, not by others well tested strats. To be honest I'll be trying VGT soon, because I feel I'm ready now.
