[quote name='boognishd']If you don't mind a little tinkering you can open it up and adjust the laser. There are many FAQs out there to help you out with it. Be aware that it's only a temporary fix; the laser just gets weaker over time. Your PS2 will probably get pickier about which games it will read as time passes.
I got another 6 months out of mine like this though, and it only took like a half hour to do it.[/quote]
I tried that with a friends PS2 that didn't work at all and got it working with most games out there, there was one game thou that didn't work so I tried it again and accidentally broke of the screw I was adjusting....
Long story short is maybe you should play it safe. If your friends isn't playing his GOW2 just ask him to swap PS2s until you finish it, shouldn't take you too long anyways...
