The F is for FUN!
I started playing F-Zero for the Nintendo 64 the other day. Having never owned a 64 before, I was interested in what all the fuss was about.
The very first thing that ran through my head was how goddamn primitive the game looked. It was downright awful! How could I play something that looked like it came from the polygon dark ages?
Not even 5 min into the game, I didn't even see the graphics. I was too worried about hitting the boost pads and drifting around corners. The controls are tight and responsive, the action, FAST!
A great game causes graphics to melt away. Who has time to appreciate pretty graphics when 100% of your attention is focused on gameplay?
Sure, graphics attract people to a game (or turn them off of it) but it is the gameplay that keeps people coming back. And a great game shouldn't be left behind because there are fancier ways of playing. If something is still fun, then play it. If it isn't fun any more, start looking for something that IS fun.
