How to install Spore under 10.5.2!

 * Insert CD.
 * Using Terminal or something that can see invisible files, copy the whole contents of the CD to your hard disk, to somewhere like /Spore/.
 * Go to /Spore/SPORE\(TM\)\ Install.app/Contents/Resources/
 * Open tgInstall.plist
 * Comment out a bit here like so:
{{{
<key>InstallVerify</key>
<array> <!--<string>$INSTALLVOLUME/installer/INSTALLDATA.tgz=6352d7a8f78e9750444ba8aa26806a7201dd66fb</string>--> </array>}}}
 * Find/Replace $INSTALLDIR to be /Spore (or wherever you copied the contents of the disc to) -Change the MinimumSystemVersion like so:
{{{
<key>MinimumSystemVersion</key>
<string>10.5.2</string>}}}
 * Install the game!
'''To Play: '''

 * Go to /Applications/SPORE/SPORE.app/Contents/ (or wherever you installed it to)
 * Edit Info.plist -Change the MinimumSystemVersion like so:
{{{
<key>MinimumSystemVersion</key>
<string>10.5.2</string>}}}
It's working fine for me on 10.5.2 with a 8800GT. YMMV.
