Yes.
You can not play PS3 games on a PS2 console
You need a console to play console games. Computers play computer games and a PS3 will play PS3 games or the Same for the Xbox 360 and the Nintendo Wii.
nope and xbox cant play ps3 games only the console can play games with the games with that console name at the top of the game cover
no
ofcouse!
I am 90% sure you can because i am living in England (European PS3) and to save moey i bought a few games from America so if you can play American games on a European console i am sure you can play an American game on an Asian console. I think it is the same concept as PSP games which are UMDs (Universal Media Disk).
If you mean without a ps3 console connected to your tv then no, but you can easily connect up one and play games through your console.
Yes dear you can.
no the games are not forward compatible
No, the American games will not play in Ireland if your using the Ireland consolle but if you purchase the American console and take it to Ireland it will easily play all the games that you purchased is America ( the American console will not play the games the you purchased in Ireland) If you have more questions message me.
No the PS2 can not read the PS3 Game Discs
yes you can because Australian ps3 games are PAL, AU,NZ,UK so you can play games from UK on your Australian console i have heaps of UK games that i have purchased of the internet and they work just fine on my Australian ps3
