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.
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?
