I bought, played and beat Fallout 3 on the PS3 and felt that version was great but also a buggy mess that no amount of patches could fix and at times, threatened to kill my PS3. Since I won't have a new PC until 2011, I will be playing this game on the Xbox 360. I have to buy this game. Fallout and Las Vegas together is a winning combination, like 777 on a slot machine or a Natural Royal Flush in Video Poker. 
 
What about the rest of you? Xbox 360? PS3? PC/Steam?

Most likely, 360.

360. I'm no PC gamer and I only buy exclusives on PS3.

PC unless something crazy happens. I have a 360 now, kind of. Gotta fix the X clamp, I hope that's all that's wrong with it.

I have Fallout 3 on both systems, and my Xbox versions was really buggy. But, that doesn't mean New Vegas will have the same issue. 
 
I haven't thought about which system though.

It's a game I would rather play on PC but my PC can't run it so I will play on the 360 which I am completely OK with because Fallout 3 was awesome.

360.
 
I dont have a computer powerful enough to play it at top settings, 360 I'll atleast get decent visuals and frame rate.

PC. I hope it's far more stable than Fo3.

Probably 360 since that's what I had the last one on.  That game was terribly buggy no matter what system you played it on.  So much so I was never able to finish it.

Whichever is the superior version.

360, I played Oblivion and Fallout 3 on my Xbox because my computer couldn't run them at the time, and I enjoyed the hard work it took me to get and complete everything in the game. If i start on PC now I think I would give into the temptation of console commands, so I rather not.

PC. Mods makes it  an easy choice.

Probably 360 since I own Fallout 3 and all the DLC for it.  I'm not opposed to the PS3 version, if someone had an extra one I'd gladly take it, it's mostly for uniformity among series.  It would suck ass if I let a friend borrow F3 on 360 and then couldn't let them check out New Vegas cuz I picked it up for PS3.  Just sayin.

Maybe PS3, maybe 360. I dont know.

PC but should I get it on steam or retail? are there achievements?

PC of course. Mods are cool.

" PC unless something crazy happens. "

PS3, but after awhile i'll get the PC version for mods and such.

360, thats what I had 3 on and it worked great. PS3 has bug issues, and i don't own a computer powerful enough to play it on.

PC, and the occasional PS3 title

I actually haven't decided yet...I might get in on PC because I'll have my new computer by then

360 for the moment since i don't have a very good gaming rig.  
Eventually I'll get the PC version for mods. Probably during one of those crazy steam sales. 

PC; there are hopefully  going to be mods for gameplay balancing as there are for PC fallout now.

PC, since I got a good gaming PC anything else would be stupid.

I got Fallout 3 as a Christmas present for my 360 when it first came out, and then a week or 2 ago I got the GOTY edition on Steam for $25. I'll probably pick up New Vegas for PC.

I have a really hard time playing First Person games on consoles.  I'll be picking this up on PC.  10 bucks cheaper for a better looking smoother running version. 
The only thing that's giving me pause is Xbox getting timed exclusive DLC.  But even then, it's worth the wait to have the best version.

Most likely PC

PC, i really need to brake habit of buying bethesda games on xbox, and then having to resort to VATS or melee weapons because i can't shoot shit on consoles

xbox 360

360

PC.

360 because my laptop sucks, and I don't have a ps3.

360. PS3 is only for exclusives that I want. Which isn't very much. Not only that, Fallout 3 was really buggy on the PS3 and this is Obsidian we're talking about...

Im not sure, Im not really a pc gamer but I think its gonna be alot better on PC so Id have to think about that.

IF I get this game, it will be on 360.

Given I don't own a PS3 or a competent gaming PC, I'll definitely be picking this up on the 360.

" 360. I'm no PC gamer and I only buy exclusives on PS3. "

PC. My friend Justin just bought this game on 360 and I am amazed at how awful it is compared to the PC version. Everything is just easier to deal with, vats, aiming, inventory, hot keys, auto-run, and the hacking / lock picking mini games were actually playable.

definitely pc

360. Cos its the system I own.
