The one thing that bothers me about New Vegas (on the 360) is its ridiculously low draw distance. It's a lot lower than I remember Fallout 3 or even Oblivion to be, with stuff like bridges, cranes and popping into view when you should've seen them from miles away.
Still, doing a bit of a replay with a new character during my study breaks and in the evenings. Decided to go for a Guns-focused character, heavy on exploration. I left Nipton, made my way to the Nightstalker cave near Mojave Outpost, from there found my way into Crescent Canyon (which I somehow had missed on all my previous playthroughs), emerged on the other side, fought off Feral Ghouls near the Nuclear Test Site, got ambushed by a shit-ton of high level Robots near the crashed Vertibird (managed to snag the Tesla Cannon before I got the hell out of dodge), came upon Raided Farmstead, where I was ambushed by a group of Raiders, and ultimately reached the mountains near Novac.
I was exploring there when I suddenly saw the map marker "Dead Wind Cavern" appear on-screen. I then noticed a motherfucking Deathclaw stand on the other side of the rock I was on. It hadn't seen me yet, but ED-E decided to go into full-on battle mode, and got knocked to the ground pretty quickly. I ran like the wind, back to the road, where a group of Vipers were waiting for me. I got into cover as the Deathclaw followed me down, and the Vipers wisely turned their attention to it. They managed to take a chunk off its health, but he slaughtered them nonetheless. I took out my LMG I pick-pocketed off a Super Mutant a while back, switched to Armor-piercing rounds, said a little prayer, and let the Deathclaw have it.
Yeah, it was pretty intense. :lol
