Gosh, who cares about purdy graphics. It's all so relative anyways. In just a couple years time, a kid will post how SH5 looks
so dated, then a few years after that SH6 will look
old, etc.. etc.. ad infinitum.
The best graphic card will always be your mind's eye anyways. A quick example; the AOD crew are just static pictures, yet they are as real to me (if not more so actually) than the fully animated 'robots' in SH3. All I needed was a static picture, and my mind's eye did the rest. Kinda like reading a book.
edit: and I'm about to lose it soon if I see another 'SH5 is an amazing subsim' followed by a screenshot
