Fucking good game. Glad I got this randomly on a whim.
Criticisms:
-Should be more variety of size of levels. They're all roughly the same size, with 2-5 points of interest scattered in the same sized playspace. Also just a few more types of Points of Interest would have been nice.
-While there are quite a few environmental hazards/level modifiers which are really cool - black holes, solar flares, electrical storms, gas clouds etc...why in the ever living fuck is there not an asteroid shower?
-The DLC is good but it went from lonely immersive space game to talking to a bunch of weirdos all of whom are relatively uninteresting. And you spend more time hearing the bland protag talk too, and it's just not hugely engaging. Not terrible, just meh. I highly recommend this DLC for the notable gameplay expansion but only after you notice the base game getting stale.
-Balancing issues. Clear superior options across all types of equipment: Shock rifle, beam laser, flak cannon, corrosion missile etc etc. And almost EVERY single "enhancement" that comes with a pro and a con is utter garbage. Also a few largely useless perks, but most are worthwhile.
-Music is decent but could be better and more variety.
-Final FINAL boss is a bit lame.
-Some ships need some serious upgrading to become competent.
-Collision damage is perhaps too punishing, even if close to realistic. There's only one real upgrade choice to directly combat it and it isn't worth it because it also comes with significantly reduced inertia dampening.
-There is basically no good incentive to play on hardcore difficulty aside from the challenge itself, and that level of challenge may be pushing it as the base difficulties themselves are challenging, even easy at the start. Maybe I'm just a scrub at Space Quake.
