Thanks for the tip but my point was Those types of games are pretty simple puzzley time wasters with the exception of Bad Piggies which is actually surprisingly deep, and out of the two I've played they've had adverts and micro transactions. The games you list might be really well put together and control well but to me the 3D games offer much more fun and better gameplay. To me they're worth the price premium for no adds and the 10+ hours of gameplay. I'd much rather steal a helicopter, shoot a bunch of people, get in a police chase cumulating in a golf buggy fight in Vice City rather than do a few levels of a puzzle game.
But I'm obviously in the minority when (Agreeing with the OP) all you see are the free puzzle games on the marketplace.
On a side note it frustrates me that phones are as powerful as they are these days and yet not many games seems to make use of this power.
