Actually, I must admit that I'm not "yet" playing San Andreas in RGB. I have the game right here sitting on my desk, but I haven't recieved my new PS2 yet. It is being shipped and should be here by Friday, I hope.
But the cool thing is, that the minute that I get it, I'm going to hook it up to my 25 inch Sony RGB monitor, and I'm going to go to F'ing town with San Andreas in RGB.
It is going to be freaking sweet!!!!!
Any game on the PS2 that doesn't have a 480p mode, looks much, much, much better in RGB. If the signal is going to be interlaced, then you might as well see it in RGB.
I remember when Vice City first came out for the PS2. My buddy got it, and he took his PS2 to my house and hooked it up in RGB. He was totally blown away by how much extra detail and color and crispness was on the screen.
Anyways, I just think alot of people forget about the fact that both the PS2 and GameCube, for all the non 480p games, the best picture you can possibly get is analog RGB. I think there is only about a dozen PS2 games that are 480p, so 99 percent of the library would look best on a analog RGB monitor. With the GameCube, I would say about 30 percent of the games are 480p, maybe even less, so to play stuff like the first Resident Evil, in the best possible video you can get, is on a RGB monitor.
I know that I'm always pimping RGB, but usually I'm pimping it in relation to the Sega Saturn or the SNES or the TG-16 or the Jaguar or stuff like that. But I must let folks know that the PS2 and the Cube in RGB are also awesome. With the XBOX, no need for RGB, might as well go 480p with all the games. I know that there is like 5 or 6 games that don't have 480p, we'll for those games, just don't play them.
