Yes. You can play Kingdom Hearts I and Kingdom Hearts II on the PlayStation3.
i saw one video of a dude play kingdom hearts 2 on ps3 so check
kingdom hearts is for the PS2 but it can be played on the PS3 as long as you have a PS3 that can play ps2 games because the new PS3's don't let you play PS2 games on them.
kingdom hearts could PROBABLY play on older versions of the ps3 but it wont work on ps3 slim(i have 1 myself and it dosent play ps2 games,only ps1 games)
no
no not yet But they are making Kingdom Hearts 3: The Keyblade Wars for Ps3
To play any PS2 game on a PS3 (Except the new SingStar games), sadly enough, you have to get an 80gb PS3. Hope I helped.
The game Kingdom Hearts 3 will be coming out for the PS3 soon. This will be a very popular game.
No, but square enix said kingdom hearts 3 might have HD graphics, so it will probably be on PS3.
Yes
You cannot play as him in kingdom hearts 1 but you can in kingdom hearts: chain of memories.
PSP and PS3.
