My dad was really into computers when I was a kid and he brought a Commodore 64, and an Atari home for us to mess with as soon as he could scrape up the money.
So video games were a thing in my life going back over 30 years and I remember Pong, Frogger, Battle Zone and a bunch of other games that basically amounted to moving a square around a monitor or tv screen.
Now a days video games are immersive worlds with big money involved in the voice acting, story development, and effects that are unbelievable compared to days past. I don't have a ton of time to play them as I'd rather be outside, but where some folks watch an hour of tv before bed, I play a game because I can influence the outcome in truely well put together games, the character development can be well done, and they can be quite cinematic. The Mass Effect games come to mind. Crappy games have one outcome, and I'm not a fan of first person shooters for that reason.
Innacurate portrayals of guns do annoy me a bit. Sci fI or fantasy games, not so much. You've already accepted a hokie story so just role with it. However, historical inaccuracies and poorly thought out incompatibilities do tick me off a bit. But you know, it's a game, so who cares. I'm a lot more concerned about inaccuracies in the media and political field today than in entertainment.
I haven't had tv since 2007 and I don't really miss it. The marketing and nonsense of that form of mass media does nothing positive in my mind. I do miss the Discovery and History Channels, and PBS stations though. What I do have is a ton of DVDs and blue-rays. I love movies and well done series that have a long ongoing story. Watching season one of Game of Thrones compared to season seven is kind of funny.
Firearms innacuracies in movies and tv can get a little annoying, but I find the portrayal of physics defying bullet impacts far more irritating. I find the portrayal of fully automatic rifles having zero muzzle climb particularly annoying. Someone unloads a 30 round magazine and the gun just stays on target? I gotta get me one of those.
It's all just entertainment so if you're getting that wound up on the details, you probably arent enjoying the story. As others have said, you have to have a strong willful suspension of disbelief to enjoy character acting of any kind.
My most recent one was in the Novel "The Drawing of the Three" in the Dark Tower series. A gun someone is carrying is described as a "Ruger 44 Automatic". I'm pretty sure Ruger never produced an autoloading 44mag pistol, and if they had it would probably put the Desert Eagle to shame, given Ruger's rep for over building guns. So I just assume King meant to say a 45 auto. King also has a part where the main character Roland is looking for rounds for his revolvers and he acquires 45 Winchester rounds. Umm, 45 Winchester isn't a revolver round, and certainly wouldn't belong in some old SA revolvers. How about 45 Colt mister King?
