Well, if you was given one hardware set to work with for the software, you'd probably get many things done against anything else on the idea. The thought of being able to get more of it for the fact against less of something else, is on the idea of probably more direct then indirect, cause who wants to make something that would just crasha system probably for the fact of working?
Otherwise you;d just be able to cover more the hardware and software and where would the next development and/or sale be at? And with Multi-player being the bigger parts of things to take off at, and work with. The limitations speak for themselves. But saying Avatar graphics would be a limitation, would be to say, you'd get the in-depth development within other releases at times with the graphics. Something like Avatar graphics would say, you would need it though given, the detail in it all would explain itself.
But on thoughts of more, probably isnt enough, so to say, it would be something worth the fact of it, would be to probably say that there isnt anymore to work with at all. Which probably last to the point to say it only and only for that point.
A.I. For a GTA example, is interesting. Especially on the idea of that, you probably havent gotten in a gang war yet, and the cops probably havent found you either. Some pedestrains have guns, but some dont. And to say theys a differences between a pedestrain and a gang member after awhile, is probably far and inbetween. So for AI, to say, should be interest for where any developments will be at for many things.
Think the idea of high-end graphics of "granny" beating away at with a purse is better placed when another "gang" member comes up and robs you. Then takes your car you stole. While trying to complete a mission to rob someone else. But to say, there couldnt be some more A.I. for that, who knows. But we'll have to wait and see of course and hope there isnt anything to out there, even for kinda "bogy" gameplay to say.
But dont worry, you still end of going to jail. Broke, weaponless, and still on the same mission. Idk, but for something to look forward to on the idea of examples to say for the new Xbox, rather GTA is a good, who knows. Usually any good release has better graphics as an interest against things, probably that are more of a playable option or feature set. A.I. tends to be environment alot, many here think as well. For some thoughts, idk. Rambling. Should be good though.
