The question has never been, "what can you do in Gran Turismo 5 ?" The question, especially after obtaining all the information we currently have, is "what can't you do in GT5?"
We know there will be a horde of cars and more tracks than ever before; the total sits somewhere around 60, although this may include different race layouts for the same track. There's just no denying that the fifth installment in this critically acclaimed franchise will be the deepest and most authentic but perhaps you need more; maybe you require a bit more in the way of individual customization. Well, how's about some nice track editing? This feature has supposedly been confirmed in a recent European video straight from the DigiExpo. If you're not fluent in the language at hand, the translation for the statement that pops up about two and a half minutes in is simple: "you can make your own tracks." Of course, this could be open to interpretation and it's not like Kazunori Yamauchi himself made the announcement, but it's a good sign. Personally, I really like the idea of creating my own track; I'd place it along the coast somewhere and make it full of complex twists and turns. Don't get distracted by the scenery 'cuz you'll have to pay attention to the hairpins!
Creativity and imagination isn't often utilized much in racing games but when we start making our own tracks, the sky's the limit. Let's just hope this proves to be true.
