Steam Summer Sale - Top Deals

Initial scrolling of the Steam Summer Sale seems pretty lackluster, but digging through the comments sections in other threads, a few gems have stood out, and it doesn't appear we have a thread dedicated to this yet, so post what you think are the best deals here!

Not mandatory ofc, but it'd be helpful if...

• One game per top level post, so comments stemming from it are focused on on just it.
• Hyperlink the game title to its Store Page
• Include both the normal and sale price / %off
• Include a short blurb about the game - if it's one you've played before, what did you like about it? If you're diving in blind, what grabbed your attention?

Good hunt'n!
