Ratchet and Clank: Quest for Booty is an indie game? I never knew!

Wipeout HD? :O

"Insomniac Games confirmed that there will be a download code for this game for all physical copies of Ratchet & Clank: Into the Nexus."

From Wipeoutpure HD wikipiedia page:

Retail 

• ^EU 16 October 2009

Nevertheless we can start adding some exceptions to the rule.

A download code to get it for free with a future title that was released years later hardly means it wasn't a digital only title (though it did get a retail release in the EU)

Also Wiepout HD retail was EU only, and was over a year after it's initial release. If a title comes to retail later does that mean it was suddenly never an indie game by your defintion?

Infamous First Light would be another exception to your rule.
