Quote - Whoa, if any of you have a steam account, I just spotted Silo on summer sale for $29.99... crazyyyy!  http://store.steampowered.com/app/100400/

 

Just a warning about steampowered ...

it requires to have Steam installed and running in the background everytime you use it.  This also means an internet connection when you go to buy it and install it.

And while Steam supposedly runs offline after activation, it is also prone to a “bug” (quotes very deliberate) that makes it impossible to run Steam offline. I literally had to change code in a config file to fix it so I could play my already-purchased games.
