I know this is supposed to be a faithful recreation of the classic X-Com game, but I think it should be realized that X-Com: UFO Defense was more of a "science-fictionized" setting than what Xenonauts is put in to. The starting weapons in X-Com were tailored more towards this, having more of a sci-fi feel.
In Xenonauts, however, I think a chance should be taken to bring some more "realism" into the game's armory.
Here is what I'm suggesting
I consider myself a bit of a weapon's buff, and I love it when weapons in video games are given brief and detailed descriptions. In Xenonauts, however, there is only one rifle that is considered to be the universally-accepted standard-issue assault rifle of the Xenonauts program: the M16A1.
See, I like having immersion in some of my games, and I feel like Xenonauts has the opportunity to add in some more weapons to tailor to nationality or somesuch. It's the late-1970s, right? The Soviet Union is in on the Xenonauts initiative?
How about add in the AK-74 model into the fold?
It's a bit jarring to see a Cold War-era Russian soldier carrying around an M16 assault rifle, I'll admit.
