I've taken note of your key phrase 'Circus Electrique instal the last version for iphone' and also analyzed the provided text. Based on my findings, I can tell you that Circus Electrique is a game developed by Zen Studios, not an iPhone app to be installed.

The game is set in Victorian steampunk London and combines elements of RPGs, tactics, and circus management with a unique twist. The gameplay involves saving the city from mysterious events where everyday Londoners turn into vicious killers, using the special talents of performers like Strongmen, Fire Blowers, Clowns, and others.

You mentioned your concerns about Valve's monopoly in the gaming industry, but this is not related to Circus Electrique. However, I'd be happy to discuss this topic further if you're interested.

Regarding the game itself, it seems that there have been updates and patches released, including a recent one that addressed bugs and feedback from players. One player mentioned being confused about rewards in training grounds, which can make the content too easy when fully utilized.

If you have any specific questions about the game or its mechanics, feel free to ask!
