Your points aren't quite valid. Those things are fantasy with no real world counterparts. We don't fire Star Trek guns most of the time. Stuff like the Vex Mythoclast were left out by the OP as they are fantasy. The guns he's mentioned are modelled on real world guns, and have geometric impossibilities built into them that [i]break[/i] the fantasy, rather than adding to it.

Actually my points are completely valid if you think in proper context. In a science fiction movie you shouldn't question how things are done because it is fiction there are aspects that go against physics but we take it as a different place than reality. Star wars is a fantastic example of how we could examine some and destroy it by using facts, but instead we allow ourselves a disbelief for enjoyment. The at-st walker is something that could very easily be in the realm of possibility but physics dictate that as it was seen it would not work, there was no counter balance to allow it to walk. But when I watch star wars I ignore that because it is science fiction not science fact. A game such as this can take something from reality and alter it however they please because it is fiction, a fantasy game that only has a slight basis on reality. I am an engineering student and a huge gun nut, I could allow all this to bother me or I could realize it is science fiction set hundreds of years in the future and know that perhaps there is more to guns in the future than there is now. Remember if we would have told people 600 years ago what weapons we are firing now and how they would we would have been burned for witchcraft. Theories of science are constantly changing, thus they are theories and not law. What's to say in the future they don't make projectile based weaponry that's entirely different from now. To recap it is science fiction, just go with it not being science fact. Also it's the future, don't base how it works on weapons from today.

Your points here are better, but again the argument isn't sound in relation to these particular points. Okay, At-At. It's easy to explain it as having some anti-gravity generator that counter balances it or some crap (I'm not quite sure what you mean by it wouldn't work, it sure looks like it would be just fine. Anything quadrupedal is surely not hard to balance). Star Trek again, they have made-up technology to explain every detail of what happens, that's great! We have no real world counterpart so it's PURE fantasy. What we have here is guns, things that people can see and use every day, that require bullets to make 90 degree turns within the gun, in order for the bullet to escape. You can make a gun in destiny with bullets that can turn corners and I'm fine with that, that is fantasy as we have no real world comparison. What we have here is weapons modelled very well on real world things, but with massive obvious and unnecessary impossibilities. The big thing about me agreeing or disagreeing with people here is whether a feature ADDS or DETRACTS from the fantasy... Star Trek, food from the replicators, so food from energy. Oh look, we have near unlimited energy from the warp core, sweet. There's a scene in Star Gate where a team is in a ship heading for a crash landing on a planet, an ally opens a hyperspace window [i]through[/i] the planet (just a short window), that's fine, pure fantasy. What we have with these guns is in effect the ship plowing straight through the planet and everything being fine.

Well first I was talking At-st the 2 legged Variant I fully agree the at-at could work. But I digress. I could very easily explain several of the guns just off the top of my head. Barrel at the bottom of the cylinder with hammer still on top? Hammer is still used for a double action trigger and is linked to said action but it does not mean that it contacts anything with the firing pin. The firing pin would be lower in the weapon but the hammer could be connected midpoint to a secondary hammer the actually contacts the firing pin. It would be very poorly designed I agree but within the realms of possibility. Barrel in the middle of the cylinder. This is the future again, what's to say there isn't a secondary loading device that moves the round to the center before firing? illogical design yes, but possible. I could do these all day as they are fantasy based. Be creative and remember that hundreds of years have passed, possibilities are endless.

Your firing pin ideas have occurred to me, I just find the whole thing unsatisfying. They don't do anything, you know? Like Nova Bomb could instead have just been some small single use hand fired rocket launcher, that would be boring. Space Magic is exciting and fun. Some weirdly, almost impossibly placed firing pin is just dumb. It doesn't make me go "ooh future", like Hard Light or Vex, it just makes me squint at it confusedly.
