While a bit on the easy side, SteamWorld Dig is an addicting and unique experience featuring heaps of replay value.
Basement Crawl tries hard to recapture the magic of Bomberman but has a hard time with its horror theme, lack of a real tutorial, and online connectivity issues. Overall, Basement Crawl can be a fun game but it's hard to justify a purchase when half of the game just doesn't want to work.
Red Barrels' Outlast is a solid indie title, which provides tension and scares in equal abundance. And while it lacks the sort of story depth a lot of us have become accustomed to, there is still a plethora of terrifying fun to be had. Get it on PlayStation Plus as soon as you can.
Warframe brings a new and addicting experience to the PlayStation franchise. Along with great and fluid combat, this is a free-to-play title that will justify microtransactions in a positive way.
