this is what WPCentral says ....rodeoz said:^^ It can work on 512MB RAM phones as well. Just that it hasn't been made available for WP8 phones. Some WP8 games released with 1GB criteria in the past were later made available for lower spec phones as well. I think Temple Run will eventually make a cut too.
