The biggest hurdle that the PS3 will have to overcome.

[KBG29]

Now on two how Blu Ray can help a none sim game. First and formost all PS3 games will be 1080p by 2009 Itigachi and the Lair devs have both started it is very possible to do. This alone will take double the disk space of most 360 games in the art department. Higher definition is not even the start though of were Blu Ray adds to game. First you have all I mentioned in the post above and it just goes on from there. With DVD a developer is limited to the amount of differant textures they can use so you will see a lot of the levels taking place in very similiar places, just like you did with big games last gen such as MGS, GTA, Getaway, killzone, and Halo. All of these games had to go with a theme to thier look because they could not have a lot of differant textures, this is why MGS three is only in the jungle. Now with the Blu Ray and the ability to stream textures devs will be able to eat away at the disk like their is no tommorow filling it with a gigantic amonts of textures.
