How does ECM, which is an anti-radar system stop our infra-red radars from working which are heat based? Also, ECM emits radar which would still give you a heading.
Drew made a point on this earlier. Just because it uses the same name, doesn't mean it is the same technology. What does ECM stand for - Electronic Countermeasure? You list one kind of ECM why does it have to be exactly the same thing in 3300? As long as it is electronic and it is a countermeasure, it is ECM. For all we know it could be a poorly wired electric blanket that just so happens to emit a quantum disruption field perfectly attuned to vibration levels of most major missile manufacturer models.
We grew up with lasers that go pew pew for cripes sake! I have yet to come across any lasers whether commercial or scientific that even 'pew' once let alone do it twice when you turn them on. I admit, if they did, powerpoint presentations would get more interesting.
Lets try some realism:
Lasers - a little light on our console flashes when we pull the trigger to tell us they are firing and a readout tells us if they are getting too hot. The canopy HUD shows an icon to indicate where the laser it contacting the target. Even more realism is that we target the craft by choosing from a menu and the computer does the rest and lets us know when it has finished.
Projectile weapons - banned by most civilisations due the concern over the dangers of future collisions with high velocity objects
Canopy - We don't actually have one. We have a cockpit hidden in the bowels of the ship with heavy radiation and blast shielding around us otherwise we would fry or die of radiation poisoning. Everything we see is a projection or screen from external sensors/cameras.
Piloting - other than under extreme circumstance we are not allowed to take manual control of our craft due to safety protocols. No government type is willing to allow manual flying of huge vessels anywhere near civilian populations without strict adherence to flight paths/plans
Trading - When we buy or sell something we wait for many hours while it is loaded/unloaded
Battle - we die due to the complete superiority of automated battle systems when compared to our pathetic Mk1 eyeball and human reflexes
Sensors - we have an entire room dedicated to the sensor suite which is powerful enough to picture our surrounding for hundreds or even thousands of kilometres in every direction. Pilots do not navigate they simply follow the instructions of their commanding officers.
Sensors in battle - except for extreme circumstances, close quarters combat doesn't exist
Speed - there is no upper limit. Except in extreme cases, battle is long-distance and is over very quickly or revolves around jousting over extremely large distances due to the time taking to accelerate/decelerate. Collisions are invariable fatal for both parties.
Some examples, you could make these even less interesting to play if you add even more realism to them. Preety certain that if we get truly 'real' we sit in a metal box playing spaceman via spreadheets waiting for the computer to tell us if we have arrived or if we died yet.
