Sound and video cards for PC games with a laptop? can I even use them, or do I even need them?

I'm sorry I'm such a n00b, I am trying to play American Mcgee's Alice for the first time. Just installed it, but it won't work. I guess because I don't have a video or sound card? But I just looked it up online and it seems you can only install them into a PC (and they're pricey). How do you play games on laptops? Or are there special sound and video card plug-in type thingies for notebooks?



Please answer,

and thanks in advance
