Observation combines an excellent narrative and presentation with some often cumbersome gameplay elements that really drag the experience down. It's absolutely worth seeing through to its conclusion, but it may not come easy to the impatient and unforgiving.
A Plague Tale: Innocence isn't the largest, most expansive game you'll ever play, nor does it accomplish new things in the areas where it does place its ambitions, but it's stronger for it. It's a focused story-driven experience completely free of bloat or unnecessary attempts at lengthening its runtime, and knows exactly what it wants to do. It delivers an emotional and effective tale, while also implementing simple mechanics in constantly engaging ways to make sure that it's not always all about the story.
Sniper Elite V2 Remastered is a conflicted game. It's one part phenomenal sniping experience and one part clunky, run-of-the-mill third-person shooting gallery full of awful AI. If you're able to overlook its glaring faults, there's fun to be derived from its attention to realism in its sniping and its brilliant bullet cam gore, but overall, the one's best left in the past.
Earth Defense Force: Iron Rain is a marked improvement over its predecessors in spite being a spin-off by a different developer. Fans of the series will definitely appreciate the additions made to the game while still retaining what made the series so enjoyable. If further installments are able to improve on what Yuke's has done with the series while also fixing some of its issues to bring it up to speed of other modern shooters, it could expand the game's market well beyond its cult following.
Borderlands: Game of the Year Edition is more than a blast from the past - it's a compelling game in its own right. Though it serves as more of a base for greater things than a pinnacle for the genre, there's still plenty of shooting, looting and Vault Hunting to be had.
