Except you don't get to make the game decisions either. That is up to schema and the devs. They listen well to the player-base and from what I am seeing there are more people here saying that this is a ridiculous notion more than those that favor it. Someone stated this above. Go play deadspace. I agree. That is a game where you can EXPECT that sort of atmosphere. I have never thought of starmade as a game where I would encounter the sight that you described. It suits those games better because frankly, low res blood splatter on a wall doesn't frighten me, or add any sense of tension to any situation that I will ever encounter in starmade.
Up until this point there hasn't even been a major interest in astronaut exploration/combat because we:
had 1 weapon to use
and never encountered npc's
Had blood, gore, or violence been the core of the game, these features would have been in a lot sooner and developed further than the current state they are in. I CAN state that I know what starmade is about because after over a year of playing the game this is the first time I have ever had to question whether graphic imagery was necessary for the death sequence. This is because I knew that they would have been made more apparent than they were now if it ever was to be a focus of astronaut mode.
In terms of physics, anything that cannot accept and disperse energy that is put into it can explode. Phasers could blow up rocks. Not because of kinetic energy, but because of thermal energy. Any weapon can blow up anything if its projectile can put in more energy than the target can take. But seriously... they are lasers. Every member of this community knows what a laser is, knows that they are in the game and knows what lasers do to flesh or for that matter, anything a laser touches. Scorch marks on metal. Burns wood. Cauterizes flesh. How is this even questionable?
The game was never intended to be used for making race tracks on planets. Players found a way without the use of actual wheels, and with a little imagination, they are able to enjoy themselves on a racetrack. They didn't need all these new features to satisfy their desired gameplay.
The entire scenario you described is straight out of deadspace. That's great. It would be cool. Frankly I don't care to experience that yet. If I have to then I will install a mod for it. But there are better things that the devs can focus on than your aspiration as to what astronaut mode "needs" or what makes gameplay fun for players. Honestly if it is so important then how did we get this far into development without it?
