Batman: Bad Blood packs a punch -- it's very well-produced from the ground up and is an engrossing and fun movie. The home release hits all the right marks and offers a solid value for Dark Knight fans.
Slice It! has a lot of the check boxes for a good eShop title covered, but I found it too challenging and simultaneously not fun enough to want to play for more than a few minutes at a time. Your mileage may vary though, especially if you're into puzzlers and geometry.
Gravity Rush is captivating early on and maintains that level of interest throughout. It's addictive, well-paced, fun as hell, and has a nice steampunk world with a great soundtrack. The remaster is good, although straight-forward, and at $30 it's a purchase well worth considering.
Normally when you think of a mobile version of the game, it's a stripped down, "flimsy" version of the console version, but Superchargers on iOS is quite impressive. The Starter Pack is a solid value for anyone that does not have the option or interest in playing on consoles, and I think you may find as I did that the portability of playing on iOS is very convenient.
