Difference between Rainbow Six: Vegas for PS3/360 or PSP?

I am thinking on buying it for my PSP. and i have seen previews and gameplay for PS3 and it looks great. I know there is a difference in graphics but how about maps, missions, features, arcade mode, multiplayer, and especially scenarios.

Oh yea and if you can, can you please tell me the places in Las Vegas it shows like the casinos, what parts of the strip, and other fantastic places in Vegas



I know long question

And thank you so muchDifference between Rainbow Six: Vegas for PS3/360 or PSP?
If I were you I would get the 360 version, I bought the PS3 version and exchanged it for the 360 version. There's no difference in maps or any other feature, but there is a HUGE difference in online play. There are way more people playing the game on XBL and the connections are way better. Plus I prefer FPS with the 360 controller. Also, another huge difference is the framerate in the PS3, it is slow, it might be a tad bit better looking, but it runs slower than the 360 version. If there are alot of explosions going on, the game will start to slow down. Even sound effects on the PS3 version don't register, like if I were to fire off some rounds with a sub machine gun, parts of the time, the gun won't make any noise. As for places in the game, you are totally away from the strip, no big name places/hotels/casinos that were in the first game. I don't even recall ever seeing the Las Vegas strip in the game at all.
