Instead of starting yet another thread, I'll chunk my observations in this thread already begun.
Howdy. I'm Isaac, a gamer since the Atari days. I've played them all right through WC4 (but please don't ask me about that WC movie...)
First impression - Should I be getting this for free? I've played a lot of freeware and payware games, and this game is bigger and frankly better than a lot of payware stuff I've played. I keep having the uneasy feeling I'm stealing from someone... and I do not run cracks. (Insert a lot of comments from smarties about "If it will make you feel better I'll happily take your money" here.)

But I still find myself wondering if it's legal to get this game for free.
Second impression - I hate, I hate, I HATE escort missions! But I like this kind of game, and escort missions are part and parcel of this game type, so... *sigh* I get through them.
Third impression - HAHAHAHAHA! Sometimes I have to play a mission twice simply because I'm laughing so hard I can't shoot straight. Great dialog, just great! The House character was spot-on, and I know some people in real life who are just like Avatarr. My favorite wingman for dialog has to be Assassin.
(Speaking of which, could we make a thread listing all the in-jokes and pop culture references? Or would that spoil it for those playing the game the first time?)
Fourth impression - Man, y'all really got into the characters' thoughts. Little touches like the bandit saying "yeah yeah yeah yeah yeah what's it say in your manual about THIS?!" which would be what a real pirate, scornful of real confed pirates, would say. (Or something Todd "Maniac" Marshall would say... he's always criticizing Blair for "flying with one eye on the regs manual." Maybe Maniac would make a good pirate?) All in all, very well developed characters.
Fifth impression - Man, there are some real downers. Not that this is a bad thing, it's essential to the storyline, but my heart almost broke when the Wellington finally bought it. After all the hard work I did to save her... And losing Vega was a real blow. You folks did some great writing there. The player actually cares what happens. I like to think of myself as objective and slightly cynical, but you even got ME caring.
Sixth impression - Some of these missions are really hard even on very easy. Maybe some added dialog would help... like in the mission where you have to take out transports before they dock with Blue Point, might have a wingman mention "Just go for the engines, we can scrap them after we stop them all." And don't get me started on the skipper missile... how are WE supposed to magically know how far behind the Battleaxe we should hang around? I had to check the forum more than once to get past a mission, but by the power of the mighty Google I made it through.
Seventh impression - Ahhhh, Excalibur. This is how fighters should be! I finally get my coast back, AND auto-tracking guns!
Speaking of which... why can only the Arrow and Excalibur coast? It seems illogical that Hellcats, Thunderbolts and etc. can't coast. There is no friction in space, assuming you don't run through a gas cloud or something. There should be an in-game explanation for why coast is not available in those fighters.
Eighth impression - Capships are far too easy to kill, ours and the Kilrathi. If they are really that easy to take out, why are they so important to the war effort? One fighter (me) can take out multiple destroyers, corvettes, etc... And they seem somewhat worthless. I have never yet seen a destroyer destroy anything unless it's scripted. If that's the case, why not just send out waves upon waves of carriers loaded with fighters? Why bother with all those other smaller capships that can go down so easily? Just IMO. This is something I never understood in the official WC games either, so don't think I'm just picking at you guys.
Final notes: All together this was a well rounded, quite polished and professional game you have here. It fits right into the WC universe too, from the gameplay to the story. You could be selling this thing, or you could contact the company that owns the official WC copyright and sell it to them. But for my own reasons I'm glad you're not. Thanks for a great game!
