*** welcome to the forum

Admittedly, i only became a fallout fan after playing fallout 3. Having never even heard of fallout before. So im kind of a late joiner. However, that doenst mean im not a fallout fan. I tried playing the other two ( like you ) but didn't enjoy then at all. I guess there just too outdated for someone like me who is used to all the high definition and graphical games. So, meh. Goodluck, but if your only playing them to enhance your fallout NV experience you might be disappointed.
That's the same for me as well. Back in my younger days, I do recall my friend and I loading up Fallout on his computer. And I'm trying to remember how many colours it was... I'm thinking 256? We were pretty happy with that cause it was looking a lot better than Wasteland!! Although Wasteland was pretty cool, but I don't remember it much. Except for something along the lines of reading the red mist or fine paste sort of thing! lol Actually even when FO3 came out, for some reason because of how it was advertised I assumed that it was more FPS than anything. So I actually avoided it for a while, until a friend of mine who owned it said it wasn't. I rented it first to give it a try... and I was immediately hooked!! Needless to say I went out and bought it right away.
To the OP... I don't think I'd be able to sit through playing F1 and 2, although it would grant me a lot of background story in the series. I'm just going to piece together any background bits that appear in New Vegas and hope they make sense to me!
the reason i wont get the game right off the bat is because i played FO3 on PS3 and i have 2 friends that played it on PC and said it was way better on it. so im going to wait until i get a new monitor (52 inch LCD screen) for my computer (im pretty sure my comp will run it on high settings) and a gaming mouse and key board. i don't really see anything special about the preorder packs so im not all that big in a hurry to buy it.
Whoa.... do you literally mean a 52 inch MONITOR? I can completely understand running that on a TV, and sitting on your sofa. Is that the kind of setup you're going for? If you're using that solely for your computer, how close will you be sitting? Also, if you're going that route.... I'd 100% recommend that you go LED.
