GeoGuessr runs for 5 rounds, shows Street Views from all over the world, but doesn't give you any options for changing the game. You guess by clicking on a map. It seems to have a limited number of pictures, and a definite bias for certain areas.
The second, Locatestreet, allows you to choose particular countries, or areas within countries. You have a multiple choice for area (state, for instance), and then click on a map for a more exact guess. I have yet to see a repeat picture.
I've learned several things from this game. Flat, dry landscapes tend to look very similar to each other. Slightly run-down suburbs also are difficult. Is there a car up on blocks? If it's hilly country, guess Appalachia; if it's flat, go with Mississippi/Alabama/Louisiana (sometimes it turns out to be western NY, though).
On a different subject, if you like well-written, near-future science fiction TV (at this point, I assume I've lost everyone who reads this blog) you should have watched Orphan Black, on BBC America. Thoughtful, did not brutalize the science, and very well-acted. The season (10 episodes) is over now, but I assume they'll repeat it.
