Tomorrow as I am flying across the country, I shall (at least for a bit) be playing Etrian Odyssey.
I find playing an old-school dungeon crawler at 34,000 feet amusingly ironic.
If you filed off the serial numbers and re-worked the graphics and (minimal) story a bit, you could call this the Bard's Tale IV. It's hard, it's tricky, and it Wants You To Die. It doesn't actually cheat, or at least I haven't seen it cheat so far. But be careful opening doors if you're not ready for what's on the other side.
What's almost as intriguing as the game is the reaction it has received online.
You can't have reward without risk. It's almost a law of economics, and it is incorporated into our psychology at a deep level. Witness gambling or extreme sports, and those are just two of the behaviors you might think of where almost the entire joy is in the taking of the risk itself.
(Warning, this rambles.)
