My best deal was buying a used COD: MW3 on ebay. What i do now is sell my used games on ebay, and just buy another used one. I don't feel like paying full price for a new game. Makes no difference to me. Gamestop is overpriced too.
My favorite game on the PS2 is Marvel Vs Capcom 2. Being able to control all my favorite marvel superheroes and villains was awesome."
2nd favorite is Final Fantasy 10. I was obsessed....
I spent the most time on my super Nintendo playing Mario and Kirby. Playing pokemon red on gameboy over and over was super fun...I prefered the gameboy as a kid though, since I could bring it with me to the bathroom LOL.
