I'm running one in Y and I cleared three gyms in two days with level 40 bugs. If you want a challenge that'll make you change your tactics, I don't think the game matters much. If you just want to see what happens, I'd suggest x/y. When you're tired of grinding, you can change your trainer look or do battles with Earls.
what about the camera? Can i use any kind or is there a special cord for it?
I don't know if you can shoot a video of your gameplay using a 3DS, but I did learn of equipment that may have already come out; The NEW 3DS. If you wanted a portable gaming system, stick with what you've got. If you wanted to record things and upload them or something, this is the new (and expensive) gadget to own.
An augmented Kastura card (So you don't have to McGyver it) and explanations can be found
HERE. I don't know just how expensive it is though.
If you don't have a swimming pool made of money; The McGyver method. (Camera..perhaps with an Iphone 5, mic, earphones, two weird jacks, and a scary looking setup to start.)
Same Youtube guy.
If you're not afraid of a challenge, you're welcome to mod it. If not..a review of the store offering the kit and systems pre-assembled.

Aside from all of that, I think you're stuck with a webcam. I just don't use one myself, so good luck?
