After posting this topic, I went to play a few rounds of Rainbow Six Vegas (for the psp). Apparently, they have shut the server down due to user inactivity. How common is this? Is there a list of games servers that aren't up and running anymore? Why on earth would they support it in the first place if they just plan on dropping it?
My other question is, will Ad-hoc party fix these issues? Will it act as a server for the game that you and your friends are wanting to connect, or will the games you buy have to support ad-hoc party?
Also, is it up to Sony, or the developer as to weather or not the server gets pulled?
