[quote name='FriskyTanuki']Because it can be impractical and not a good way to spend resources if other parts of the game are in better need of those resources. As I mentioned before, lag is the biggest issue, which kills any chance of action games, shooters, and other fast-paced games regularly using it. Plus, you don't really gain much by doing it since the amount of people that can or want to do it are very small.
Lair's pretty much an example of why it's not a great idea to just do it since Factor 5 had plenty of more important things to do besides making their game compatible with remote play. I'm not 100% sure, but I believe that nobody even knew it was RP compatible until a while after the game came out, so you can see how great the marketing/development resources were spent.
The whole process of sending button presses back to the game and then showing the results over a fairly slow wifi connection should be the obvious reason why it's not more common. Remote play's better served as a way to listen to music or watch videos when you're away from your PS3/TV as a simplified media server.[/QUOTE]
Thank you. Honestly, lag didn't occur to me...although given that the Go only ships with 802.11b, that's probably the primary reason.
Given that the PS3 seems to
focus on the fast-paced titles that don't work for remote play, I'm not sure why they bothered with the feature in the first place. It just doesn't seem like there are many situations where it's useful, and so far the list of titles that support it has shown that.

[quote name='starmask2k3']my mistake i didnt see them ok
and why the hell are you in a PSP Forums anyway u dont have a PSP or a PS3 the wii and the XBOX360 cant do remote play[/QUOTE]
I'm here because I
was interested in the PSPgo, and because new hardware launches are always interesting to watch. They don't happen very often, and we've
never had a launch like this. Digital distribution on this scale is entirely new...and honestly, I can't think of any other companies who have made this many mistakes prior to the launch of new hardware.
If you didn't notice, most of the people in the thread with the exception of you, TMK and a few others have been against the PSPgo, and only a minority of the people still posting here actually own the new system. It isn't just me. People like to watch trainwrecks, and as Ars Technica so eloquently illustrated, that's what the PSPgo is shaping up to be so far.
