Just those games alone makes the PS3 worth it.
I agree.
Even after I bought my PS3 I struggled to reconcile within myself spending that much money on a console at my age, even with the Blu-Ray player and Netflix app. Then I picked up Uncharted: Drake's Fortune pre-owned. I actually got more enjoyment and entertainment value out of that game than any other I had played at that point, including the Halo series. In my mind, back then, that game alone made buying the PS3 worth it. The 2nd and 3rd games were at least 200% return on investment each in my mind.
