Final Fantasy X.
Had it with a PS2 emulator on my PC, and it sucked. It took hours to go through Zanarkand. So then I bought a PS2 off Craigslist and it came with Guitar Hero 1. We still haven't figured it out, but it could only run that. I tried playing FFX after I bought it and it would freeze or not load at all. Then I tried renting a Silent Hill game, and it wouldn't load either. Took the PS2 to a city 40 minutes away that had the closest GameXchange left and they cleaned it, which didn't help. Somehow it plays FFXIII just fine though, go figure. So, I saved up another $80 and bought a PS2 from Gamecrazy and could finally play FFX, and it was worth it.
