Austin/Mark of the Ninja fans rejoice, for some reason it isn't listed as part of the present deal but I looked it up and it was half off; seems really fun so far.

agree :)

Saw that...but I can't decide between it, Enter the Gungeon, Risk of Rain, or The Witness. I'm kind of leaning to The Witness because of all the amazing things the duders had to say about it. But I'm terrible at puzzle games and think I won't end up finishing it without forcing myself to use a guide. Invisible Inc. looks very intense.

Be warned. Even with zoom on, Invisible Inc is crazy hard to read on the PS4. The font choices in that game do not translate well.
