The causeways in seasons 5 and 6 were too long. They each took about five minutes to complete... far too long to stay interesting.
I re-watched the winning quest from season 5 a couple of nights ago, and apart from the causeway and the encounter with Aesandre, the dungeoneer encountered no other opposition in level 3 at all. Definitely the worst incarnation of the third level.
Fair point, I haven't seen it in a while (read: 10 years... it's not one of the ones i have on video). but i loved the whole winteria atmosphere and the fact that it was such a cool setting and idea.
so what do i look for in a 'good' level 3.
the fire and freeze/trick and treat spell riddles were a great idea. i would have loved to have seen one backfire.
i like having one huge causeway that you have to get the code for half of it then work the rest out by yourself. i did think the series 6 'find' and 'path' was too easy and would have liked to see the roman numerals back.
i never liked the play your cards right game. it was too repetitive and there was very little chance of a dungeoneer losing to bad navigation like there was on the causeways.
i liked owen the dragon (random but a good element of level 3).
i also liked roleplaying challenges, having to convince someone to take/do/drink/give something (gargoyle, freeze potion, some of the sir hugh encounters) should have been a task for every team in level 3. because i like good roleplayers, ok
i didn't like the very heavy riddle aspect of some of the early series. you get one riddle wrong and you're out. that's more luck than skill really. i would have liked to have seen puzzles that took the whole level to solve. picking up bits of an object/spell/code was always cool in my books.
i'll think of more ramblings when i sober up.
