I'm curious and quite a bit angry at the moment about the WP7 marketplace and purchase history. On my 360 if a game is delisted or removed for whatever reason I can still see it in my download history. I can then redownload the game and all is happy, like I "purchased" the digital rights to continue using the game. I'm guessing on the Wp7 that idea is completely thrown out the window and games on that "platform" are more of a rental because if you delete a game and it has been delisted, SURPRISE, you can no longer get it.
My question is WHY? I ask as today I downloaded the newest WP7 game PES 2012. I didn't have room so I removed PES 2011 (even though I'm not finished with it) because I figured I could reinstall it after I complete a different title. Surprise surprise the game is gone and there is NO way to get it again and I'm pissed. I buy a lot of XBLA/WP7/XBOX360 content and I basically have taken the 5 bucks that was spent for PES 2011and had it taken from me with no recourse.
I would like to be able to redownload this title. Konami is still in business so the delisting is fairly odd.
