That's a really nice deal if you're missing some of the higher priced games. Some of those have lows that are near the $3 each mark, which is where you'd be with the five game bundle.
I went ahead and got Spellforce 3 and Children of Morta. That's a decent price and I think I'll play them both soon.
I just got done playing Dishonored and really enjoyed that. The Definitive Edition for $3 is a steal. DOOM's great. Kingdom Rush is fantastic and the price has to be an all-time low.
I added What Lies in the Multiverse and Before Your Eyes to my Steam wishlist because they've been that price or better before. Has anyone tried either of those?
