The 4 third-party games that have done decently - ZombiU, Sonic Racing Transformed, Rayman Legends and Monster Hunter 3 - have had effort put into them and decent marketing (although Monster Hunter 3 was only published by Capcom in Japan).
I'm surprised these publishers haven't noticed a pattern here tbh. If a title is on par with the other SKUs and not gimped in any way and is released the same time as the others and at the same price and with the same marketing push it'll make a profit. It's really not rocket science.
