No, you need PS3 controllers
yes there are no slim PS3 games only PS3 games and PS3 Move Exclusive games that will only work on PS3s with the Move Bundle installed. Move compatible games do not require the move bundle installation except to use th move controller
yes
yes
Yes, cause it's not an different console.
yes SIXAXIS and DUALSHOCK 3 controllers work on any ps3. Any controller that is made for the ps3 will work on any ps3
Depends on preference. Personally, no
The PS3 uses Bluetooth controllers and both the PS3 Move Controllers and the Dualshock 3 Controllers are Bluetooth. If you buy a wired controller it will not really be PS3 but any PS3 controller works on any PS3 even if it is not original PS3 equipment
no Ps1 games are compatible with any ps3's and definatly not with the slim sorry
yes, the ps2 rock band controllers are actually ps3 controllers but they are ps2 compatible
The dreamGEAR Shadow 6 is compatible with all PS3 units, including the new PS3 slim.
The PS3 that were Backwards compatible are being refurbished and sold from places like Gamestop. Production on earlier PS3 models of all but the newest PS3 slim has stopped. I have seen new PS3s being sold on Ebay that are Backwards compatible and they are going for twice what the PS3 slim sells for,
