what are the bugs like? I've read reviews that say they almost ruin the game... is this true?
I'm contemplating getting the PC version....
Let me try to explain it as I see it (mostly from hovering around the official forum which has pretty much descended into warring factions, much like the game itself). There are 3 groups of people with differing opinions on the game.
1). A minority of console gamers mostly in the US who were hit with a number of showstopping bugs on US release day and had to wait a few days for a patch who were very vocal about their complaints and still aren't happy, a lot of them also don't like other elements of the game that make it more RPG than FPS such as weapon modifications and having an inventory, and experiencing an occasional small graphical glitch of the type common to that game engine, they just can't cope with that sort of thing.
2) PC Players who are morally/ethically/conspiralooniorally opposed to downloading Steam and are making a mountain out of a molehill about Steam authentication in fear that their tin hats won't protect them from this awful 'malware', and want to see Bethesda burn in hell for all eternity for requiring Steam authentication.
3) People who think the game is the best new gen RPG released in recent years and who haven't encountered any major bugs whatsoever. These people are mostly PC gamers, that version of the game had fewer initial teething problems, and that group includes many FO1 & 2 fans also.
I am in the third group. I played it for 16 hours solid in one go (yes I know that's not good for me) and 30 hours in total so far - PC digital version from Steam - and have not had any bugs or performance issues whatsoever, not in the slightest, running it on ultra-high graphics settings. Not A Single Bug.
If you loved FO3 and relish the thought of more of the same - get New Vegas
If you liked FO3 but thought it could have been darker, grittier, had a better story and dialogue, and allowed you to take sides more and have more complex faction choices rather than just playing along with the BOS and only being able to switch sides at the last minute - get New Vegas
If you loved Fallout 1 & 2 but didn't like the simplified RP elements of FO3 - get New Vegas.
It's a fantastic game, and although a minority are experiencing some bugs, patches are being released thick and fast (Bethesda and Obsidian have always been great at post-release support) and most have already been fixed. Reviews rarely get re-written to take into account the release of a patch within hours of the game being released, and therefore don't reflect the current playability of the game.
