Maybe you missed the great games of the 8-bit era, or maybe you're a parent who wants to subject your children to the punishment of Castlevania, Battletoads, and Mega Man that you went through. For you, I think Shovel Knight goes beyond being a polished, fun, challenging experience. It's a curation of gaming history in a package that's palatable to today's audience.
It would be easy to give Crimes & Punishments the typical "for fans of the genre" recommendation, but I think it aspires to and accomplishes more than that. Sure, it has some rough edges, and not every case is a home run, but the Deduction system makes it all worthwhile.
Hohokum is a delight. I enjoyed it from beginning to end, and plan to go back for every last collectible and trophy, zipping around its colorful world for at least a couple more hours. More importantly it's a real game, with satisfying goals and puzzles to solve.
Whistleblower hits far fewer snags than the original Outlast in its attempt to scare the bejeezus out of you. It's a brisk, enjoyable, genuinely scary experience, and a great supplement to the story of the core game. If you already liked Outlast there is no doubt in my mind that you'll love Whistleblower. And if you only sort-of-liked the original, well, there's good news for you here too.
The competitive game at the heart of Towerfall Ascension is still the main event, so if you don't have extra controllers and friends you'll probably want to pass. That said, it's nice that there's something fun to do with the game even when you're on your own. It's not enough to recommend the game entirely as a solo experience, but I still had a ton of fun with it and see myself going back for more, even if no one is around.
