Okay, so this is like 50/50 with the community right now. Some people completely hate it, some people completely love it. But, the Mad King's Clocktower
is a very fun and challenging Jumping Puzzle.
There are a few issues with players using pets, summoned minions, and whatever to completely block view of your character and/or jumps...but that's an MMO for you and griefers abound. Some people (like the chick in the video above) think that by going almost completely nake it gives you an edge of some kind; I find that to be an odd myth.
Also, I'd like to see them keep the Reaper's Rumble after Halloween. It's a great mini-game that trumps Keg Brawl in every way. Think a smaller DoTA style map with more player interaction and no towers. If they take it away, then the only existing mini-games will be the Keg Brawl and Costume Brawling (the latter being okay every now and then, but requiring others around you have a costume to participate).
Lunatic Inquisition is not that great of a mini-game. It's alright, but the matches are just...I don't know, I feel that it's short sided and only just a bit lacking in something. Maybe if the villager/survivor's required food or something instead of just camping in cracks and holes.
P.S. Can't wait to see what the "special event" is on Sunday.
