This game has froze my PS3 relatively frequently and has been prone to odd graphical glitches (such as doctors 360ing through the ground while speaking and proceeding to elegantly hover through walls, and at times there seems to be vortexes breaking surrounding textures and the sky) and frame-rate drops over the 50 or so hours I've played it ... so far. However, you usually experience these problems when you've played the game for around 5 hours, and your console is begging for you to give it a rest already, which is an evident indication that I really love this game.
It's rare that you can purchase a single-player game that feels so unnervingly endless, and offers such rich background systems, mechanics, lore, depth, and gameplay. Being a huge GTA fan, however, the lack of diversity when it comes to music selection on the small assortment of radio stations (2) is very apparent, and the commentator, ThreeDog, can string together different lines of dialogue that don't logically mix in an automated fashion.
There's just an abundance of content in this game, and you always feel like you're on the edge of survival; scavenging whatever you can while potentially establishing a home, links with traders, and exploring the Wasteland. You can unlock a perk later in the game once you reach the original level cap, level 20, to display all the locations in the game you can discover/add to fast travel. It will be clear to most that the game is much larger than they originally anticipated. This game also comes with 5 additionally expansion packs, with the the expansions cumulatively increasing the level cap to 30. I would recommend you do Operation Anchorage once you have the perk to carry an additional 50 pounds. You get some insanely great Armour, with a Chinese set coming with the power of invisibility.
Look, it's a superb game with a few technical issues that don't detract from the overall fun. I'm not willing to write anymore. Buy the damn game.
