Gee, it must have been close to a decade since I last played Silent Death...
The rules are a bit more involved than Crimson Skies.
It's really a "jetfighter in space" type game, a fun little dogfighter. Faster planes had an undeniable advantage though. Some of our later games became more like air races, with everyone trying to get the most speedy crafts. This is mainly because the game uses movement points to regulate movement and turning, but without restrictions on turning due to speed. So ships with lots of movement points had a lot of liberty, and could almost always find a way to line up a shot. The slower ships' armour and heavier guns didn't quite compensate for this advantage.
Maybe larger games, where you had enough planes to fly formations can compensate for this? We mainly flew small unit furballs.
I always felt the ship datasheets were a bit cluttered and hard to read quickly, a bit too much symbols and tables to reference to my taste.
It played reasonably quickly once you had a group that knew the rules and had a number of games of practise.
I'd say it's a nice game, but it definately shows it's 1990's heritage in terms of involvement of the rules and need to reference keys and tables while playing.
