This is definitely the best launch game (and that's not a backhanded compliment). Since you didn't mention the obvious comparison, to me it's Defender given the Space Invaders Extreme treatment.
Agreed, while I like Killzone and Contrast, I'd say the best of the bunch is Resogun. It's the simplest, but the frantic combat and solid controls make it stand out. I've never died and felt like the game cheated me, I always owned each death due to my own mistakes or not thinking fast enough to remember that I have some Boost, a Bomb, or Overdrive saved up for emergencies. It's just a "dumb game", but it's a solid one.
Also, it's can seriously border on Bullet Hell. Especially on the higher difficulties.
For anyone else reading this, I concur with Jim. This game is a great title for the PS4. And it's currently free to PS+ members, so there is no reason not to get it.
