What's Your Favorite Dungeon Crawl?

Coming up on the Spirit Blade Underground Podcast I plan to do a special episode regarding my personal search for the ultimate table-top dungeon crawl game. I may have found my answer, though I still need a few more play sessions to be sure. But I'd like your opinion as well!

So what is your favorite tabletop dungeon crawl game? This can be a Paper and Pencil RPG, a board game or a card game. And to encourage freedom in your selection I'm not even going to define "dungeon crawl". I just want your take on the best game for a tabletop "dungeon crawl" experience, and just as importantly, WHY your choice is such a good one for you.

And if you can't narrow it down, more than one is fine. But please also include the "why" part with each selection you make.

I look forward to sharing your answers on the show!

My favorite dungeon crawl?

For pen-and-paper RPGs I like Pathfinder. It has a nice balance of options and challenges. It's the classic structure, and can be combined with minis and models for an excellent tactical simulation easily the equal of any board game.

I also Kickstarted a little push-your-luck dice game called Dungeon Roll, and have been very happily playing this ever since my copy arrived. It's essentially a multi-player solitaire dice game where you form a party and see how far you can delve into the nearby dragon's lair. Very pretty, small footprint, lots of play options, short game length. I like it.

Munchkin. While not exactly a dungeon crawl, since there's nothing to actually map out, this game has all the elements of a dungeon crawl (okay, the original does. The expansions go in some humorous directions). It's card based, doesn't take a lot to learn the rules, the art and card names are outrageously hilarious, and the art of negotiation with your fellow players makes the game all the more enjoyable.
