Very cool interview those games look amazingly slick for xbox live indie titles, especially for 80 beans.
If it wasn't for WP7 I wouldn't have been surprised to see MS dump the XBLIGs altogether, but they don't want to burn the XNA bridge while trying to catch up on Apps.
KZ3 looks awesome so far.
Score Rush was crazy good, so many awesome XBLIG shooters out the last few months.
