I'm around ~15 hours in the game so far, been exploring most of the wasteland before getting to New Vegas (I'm in Aerotech right now) and I'm a little confused. Across all the exploring, I barely killed anything. The only ones I killed were some Geku's and some Rat Moles, as well as Scorpions. That's it. Been walking for hours through the Wasteland, finding mostly Ruined spots, and some forsaken towns. But I couldn't really find anything remotely interesting.
How can you play 70+ hours? I explored most of the Wasteland (except for two areas where there are Deathclaws, these are impossible to kill) but haven't find anything interesting. Does it change once I'm in New Vegas? How does the game get interesting after that? I love the wasteland a lot, but there is simply nothing interesting going there.
