This is not the first time I have played New Vegas. I originally played it on the Xbox 360 - I bought it on the day it came out, and played it a whole lot, but never managed to finish the last boss as I was playing on Hardcore and I just lost too much health every time.
I bought it for the PC a while back and just started playing it yesterday. I've marked it as a :B:, as I put about 50 hours into it on the 360, and 6 into this one. Given the hours I've already put into it, I'm marking this under 'way, way long'. I'll still probably play this for weeks from now, but I feel like I've already beaten it, now I'm just playing for fun.
Right now I'm at Novac, trying to find some turbines or something for the ghouls out in REPCONN. Not very far, but I've been pootling around, doing quests, getting banned from a casino or two. I've been trying to get enough cards to make a decent Caravan deck too.
Now, I have one major weakness in videogames, and that's packrat syndrome. If it's there, I have to pick it up. I keep all the weapons and armor, and use them for repair. Once I have a fully maintained weapon or piece of armor, only then will I sell the rest. I keep all aid items, and sell most misc, unless it's a weapon mod or bullet case. I just can't help it, it doesn't feel right if I leave stuff there. On the upside, this means I generally have plenty of caps floating around to spend, and if I run out of bullets I almost always have another weapon to use instead.
So anyway, Fallout: New Vegas gets a solid 5/5 stars. I love it, and I just can't get enough.
