Also I can't get over the fact that its supposedly taking place like XXXXX years in the future and they are using iron sights and basically the same kind of guns you could find today. Even the latest call of duty has higher technology going on than this.
I looked at the Star Citizen timeline. The game is set in 2945. That's nearly a thousand years. However, there could be an explanation for it. Maybe the advanced weapons exist, but it's all around more cost effective to equip personnel with these kinds of weapons. Or maybe since we're fighting in space, more powerful weapons would be dangerous if they holed whatever they were fighting on.
And also it's still a game where you need the game to be fun. Weapon technology nowadays is already ****ing scary. Firing off missiles from thousands of miles away to hit targets with near pinpoint accuracy. That kind of thing would be no fun in a game, and is why we have fighters dogfighting with each other.
But there is certainly room inbetween all that for fancy futuristic weapons. I'm thinking about Perfect Dark and the Timesplitters series which featured some very cool futuristic weapons and secondary functions to go with them and they were still fun to use. It's a missed opportunity to create some unique and eye catching weaponry. You could hand out personal shields to everyone as well and then you could have some truly ridiculous weaponry firing ridiculous amounts of bullets with the personal shields soaking up tons of damage, and if they wanted to stick with the realism thing, as soon as the shield goes down one shot can deliver the final blow. So players could tank damage from ridiculous kinetic weapons, energy weapons, weapons firing thick beams of energy, explosive ammunition, so you could tank shots from rocket launchers and the like to a limited extent, anything you can think of. Though this might be limited by what I said about holing whatever you're fighting on, there's still plenty of room between to work with. And you can bet weapons makers in the future would want to make weapons suitable for combat in space to maximise effectiveness against personnel and minimise damage to the ship.
