I remember when I first played JK2, I had a really ****ty graphics card. The frame rate was appauling, everything was pixellated, if I tried to do even x1 antialiasing it was unplayable. I begged my husband to get me a top end card and he did for my birthday. My God the difference it made was amazing. There were even effects on the force powers that I didn't even know existed.
Now I'm not saying graphics make a good game, gameplay does and always will, but good graphics can certainly enhance a gaming experience.
And now I'm off to play Little Big Planet and then watch the election results as they come in.
