I don't think you get attacked on the overland anymore. I walked the span of a couple of maps I generated and no attacks.
It's also hard to find creatures in adventure mode while traveling the world in general. It seems you can walk for five or ten minutes, going through different biomes, and sometimes not see one creature.
When you do find them, it's like there are hidden pockets of them. A herd of camels, a herd of zombie elks (that appear to be docile). No living wilderness - no birds flitting around, squirrels, occasional deer, rabbit, gazelle encounters. OTOH, Fortress mode handles the creatures entirely different - more creatures than ever show up near your fortress.
Now, to be fair, we were all warned that some of us might be disappointed with this release.
Adventure mode needs a lot of work - it isn't anywhere near as playable as the old version (though fighting giant spiders is something to experience). *But* Fortress mode is 10x better once you get used to it - I find myself liking it more and more: it is not at all like the sandbox mode I thought it'd be.
