Im about 7 or so hours into it so far. I seem to feel that I'm able to get into this installment much easier then Fallout 3 even though all the controls and user interfaces are identiacal from what I can remember. The main objective in the game is overly simplistic to me being that your only sence of drive is to track down the person who attempted to murder you in the very beginning of the game, other then that there are lots of side missions to pursure. But so far it seems to work for me. They have done a good job at keeping me into it through -- having a lot places to explore - a bunch of items, armor, and weapons to collect - killing people/animals/things with those weapons - upgradable stats and perks that help you in various ways - being good or bad in perticular towns + a karma system --. All this consitering I havent even been able to enter the main enterence of New Vegas yet since i dont have enough currency to get past the armored guards at the front gates. So im just rummaging around the mojave wasteland, occationally peering at the distant bright lights of Vegas like a moth on a window on a well lit house at night, killn stuff and collecting stuff. Til i get my 2000 bottle caps to enter, then ima be playn dem SLuhTS!
This game has frozen up on me multiple times, many of which i hadn't saved (or AutoSaved even) in the last 10 minutes. It freezes, it has slowdown, the load times get increasingly long if you don't take breaks...but it's still fun.
You can sink a ton of time exploring the wastes and checking out the locales and it's 90% of Fallout's fun for me. The quests, much like FO3 are either fetch quests or "go kill this" quests. Sometimes there's cause for stealth but not so much.
This plays nearly exactly like FO3, which is good, but it's also so similar that it becomes repetitive. The dialog is usually good, but borders on stiff when dealing with the NCR or Cesaer's Legion. Most of all, the main storyline (which has at least 4 distinct ways to end itself as far as i know) is pretty basic...revenge, the obtaining power for yourself (independent), NCR, Cesaer, or Mr House.
The bugs and the similarity to FO3 bring it down a bit but it's still a lot of fun. Explore and conquer...but after uncovering the whole map, you may think "Gee, do i really have to go back to the storyline?"
As always fallout features a stunning attention to detail and graphics and succeeds on setting the correct atmosphere. Although the amount of bugs, glitches, and freezes is much higher than most games its easily overlooked by the game play and the story line. The new weapon mods make it your weapons even better. Overall I'd say this is a must own game to be played again and again to see the many paths the story can take based on your actions. 8/10
