So... how to do this? Should every indie get a post? Y'know what? No.
I choose you, Indie Megapost. Each link below will take you to the game's PS Blog post for additional details.
The two most exciting ones are, for me, definitely Drifter...
Coming to PS4 and Vita, it's an open-universe procedurally-generated space sim! Here's its blurb:
"Drifter is an open-world sandbox space trading game with a procedurally-generated galaxy 100,000 light years across made up of tens of thousands of star systems to explore and features an original soundtrack by composer Danny Baranowsky and now it is coming to PS4 and PS Vita! (http://celsiusgs.com/drifter/) Take on the role of a spaceship captain attempting to eke out a living among the stars by trading goods between star systems, hunting pirates for bounties, mining asteroids for valuable ore, or even becoming a pirate yourself. The choice is yours!"Fuck. Yes. Is it just me or does it kinda' look like space exists on a strictly 2D plane, a'la the last (really good) Ratchet & Clank game? Still - I'm in!
Second on the hot-shit-list is Axiom Verge, a 16-bit Metroidvania that's all kinds of weird:
It... really wears the Metroid thing on its sleeve, but still! Great music!
Skulls of the Shogun: Bone-A-Fide Edition is coming to PS4, and this is probably the best trailer you'll see today:
Also, its soundtrack is frickin' amazing. I'm really glad it's coming to PS4, since I only have so many HDMI inputs in my TV, and my 360 isn't getting one of them. Maybe I'll finally play it!
Source, coming to PS4, is another Metroidvania, but it's... pretty sexy lookin'.
Spelunky is Spelunky, and that's also coming to PS4.
Chasm is a procedurally-generated action-RPG platformer, coming to PS4 - nice 16/32-bit style on this one.
Jamestown Plus is a bullet hell shooter that looks pretty cool, and it's coming to PS4.
Starwhal: Just the Tip is a game about fencing space uni-whales.
Nidhogg, the 2D very-retro multiplayer fencing indie which you likely heard about earlier this year is...
...can you guess..? Can you guess what platform Nidhogg's coming to? I'll give you a hint.
Apotheon is a 2D action-brawler that literally looks like the side of a Grecian urn started animating itself and the little dudes started killing each other. Awesome.
Ironclad Tactics, a card-based strategy game set during the American civil war (?) is coming to PS4. Meh.
Escape Goat 2, a 2D Goat-centric puzzle-platformer, is coming to PS4.
Finally, Chariot, a cute-looking 2D co-op puzzle platformer, is coming to... well, you get it.
You and your co-op parter have to move a chariot possessed with the greedy soul of a dead king through a labyrinth.
And that's thirteen.
Man, it seems like every week Sony's throwing more and more indies at us. Not that I'm complaining - I'm just wondering why Microsoft's been so quiet, lately.
