One of the highest profile iPhone games to state, EA's Spore, retails on the iTunes App Store for $9.99. Now, however, you can also get a "free" version, Spore Origins Lite Edition (iTunes link). The catch? It's teaser consisting of 1 level. Since Apple doesn't (yet?) have a model for demoing apps ("try" instead of "buy"), it's likely the only thing developers can do to give potential buyers a real preview. They hope, after one or a short number of levels, you'll be hooked enough to pony up the bucks for the full blown version.

How's this working? Well, Spore Origins Lite is not in the iTunes App Store Top 10... Pac Man Lite, which uses the same model, sits at number 5 in the free listings as of this posting, but it's full blown counterpart in nowhere to be found among the top 100 paid Apps.

What does this tell us? That people would rather pay nothing for a Lite edition than something for a full game? Or is it simply that the whole App ranking mechanism still broken?

Have you downloaded any free "Lite" Apps? And if so, how many have convinced you to move on up to the full version?
