I completely agree with you Dragonyeuw. With this caveat. To utilize that added Blu-Ray game capacity, I not only want to see new game ideas. I also want to see many of the older games redone from a totally fresh new perspective. By that I mean, enhanced story detail, Hidden plot twists, unforseen circumstances and possibilities, new character introductions. new technology utilization with superior game engines. Zero glitches. Bigger and much longer stories. This would work very well for games done in 2-3 part series like Mass Effect, Halo, Ninja Gaiden, Fable and others. With Blu-Ray, a developer could redo Halo 1-3, Wars, ODST and Reach all on 1 disc and in the proper sequence. Thay could add exciting bridging story/gameplay content. And they could creatively exploit the different gameplay styles of all 4 games across all of the platforms with new content. And as an added benefit, you would get to replay key aspects of the older games in a totally new system with new modern graphics/content.
It just appears to me that with the new system, the game developers don't necessarily have to reinvent the storytelling wheel. They have vast libraries of IP that worked or was poorly executed. Give us and a new audience of gamers, those stories in a much better way. One that is free of the tech & commercial restrictions of the prior releases. Filmmakers do movies like this very successfully. True Grit, Tron, The Thomas Crown Affair are a few examples of this. I suspect this approach would be much more successful with games. Fable 1,2,3 would be awesome if redone like that along with a final reincarnation/full explanation of Jack of Blades (was he the Devil?). That is the main reason I support all commenters who say put a Blu-Ray or equivalent drive in the new XBox.
