Yes it's packed with character and detail. The songs are great too, though work best in the context of the game rather than just reading the lyrics. One small but nice thing, if you bump into someone they will say excuse me, or something to that effect or tell you to watch where you are going. Even the coments like the explorer saying "I smell a trap" then launching himself on a bed of spikes so you can walk across his back, or holding back a sliding wall while you run by. He also laughs at you when you fall into a trap. Not bad for a "summoned" companion.
No idea if you get the explorer in the demo, but summon him in the Viking tomb for some commentry. :D
