Saw Freespace + Silent threat for $10 last week, so I nabbed them. Was addicted to Freespace enough that I finished it in 3 days, but I only did 3 missions of Silent Threat. They weren't fun missions on account of being too hard, and having dumb plots (I apologize to anyone here if they worked on those missions).
Too hard because you have to know beforehand which ships are going to jump out in the first mission or you'll never reach them in time, or because it when you blow the science ship in the second mission, all your CO says is "get clear", which really means "jump out", if you don't, you die. Terrible and frustrating design.
Dumb because, well I shouldn't even have to explain it. You don't go around blowing up your own important stations and cap ships (including a research vessel, for Christ's sake! Maybe they were close to figuring out a Shivan-killing uberweapon, you don't know) to cover up an event. Especially not in the middle of a desperate war for survival. And the third mission revolves around the science vessel's escape pods. I was 5 km away from the ship the first time around and the blast still killed me! How the hell is an escape pod supposed to survive that?
Anyway, I was wondering if it got better (it would have to be a lot better to convince me to keep slogging through it).
