I'm personally less concerned with the intricacies of firearms physics portrayal/interpretation in a computer game than I am for things like narrative, the existence of decision trees and their consequences vs. merely aesthetic binary choices that have zero real impact inside the game environment.
I'm more concerned about whether or not something ridiculous like child adoption in Skyrim will happen. I mean, like, Hi, I'm a vampire dragon killer murder hobo ... but, I have a home, so, gimme your children, because ... reasons. What was Bethsoft thinking? The feature is like soft sell marketing ploy to get money out of people with ... "interests" in children. ... and it's just creepy as all get out.
I'm more concerned about micro-transactions, which, is thankfully reported not going to happen. (huzzah!)
I'm more concerned about pointless fetch quests existing.
I'm more concerned about whether modding will be supported or not.
I'm more concerned about the depth and complexity of the writing where it seems so many many developers skimp on writing like it's a barely tolerable necessity to part gamers from their money. I want to see writing from folks that know Akira Kurosawa, Shakespeare, Sophocles, Alfred Hitchcock, and everyone else worth mention; writers that collect and are familiar with myths and stories from hundreds of cultures, that have libraries of stories in their heads they can pull from to give us countless nods to themes, devices, plots, symbology, and characters plucked from all the ripe fruits of giants throughout history.
I'm more concerned about language I hear like "padding" where people complain about a game being longer than it "should have been". WTF. What about those of us that want to play for 1000 hours? A mere 40 hour long main quest line was too long for you? I know I'm not going to see a 1000 hour long main story, but, I'm more concerned about the game being too short because of those voices in the community that talk about some games being long longer than they "should" be.
I'm more concerned about the detail of the RPG element and how it's implemented.
I'm more concerned about SO many more things than whether or not a 9mm pistol vs a .45 pistol in game perform with the same differences they do in real life.
Yes, I can understand how gun nerds will get eye-twitchy when something is misrepresented, or represented poorly. there's lots of folks due their professions, hobbies or general life experiences who get all sorts of things ruined when movies, TV, and, yes computer games don't get "it", whatever "it" is, right. For some folks it's annoying AF to see spaceships in Star Trek and Star Wars operating all in the same XY plane orientation as if they were airplanes.
Anyway, I've got way more many things to be concerned about than how guns are portrayed in a Neon/Cyberpunk fantasy sci-fi title.
