NoHeDoesn't: I totally agree. The dev's don't "have" to do anything. Sometimes listening to complaints can lead to a better game; sometimes it just leads to a watered-down game with none of its original flair.
Having said that, I do think that the devs should at least listen to these suggestions. After all, if lots of people are making them then there might be something in them.
Personally I like the randomness of which weapons you pick up. I like knowing that I need some kind of weapon and saving up for it, and then seeing what turns up at the next store. I might get something I never expected, and have to alter my build around that, and that's part of the fun. Today I discovered, by chance, an entirely new weapons build, but the only problem was that it took so long to charge weapons that I might never get a shot off. The problem was solved when I managed to pick up a cloaking device, which allowed me to stay hidden while they charged. The randomness forced me to accommodate certain weapons that I wouldn't otherwise have used, and I then had to compensate.
But, it's evidently possible that I might never have found those (or indeed any) weapons, and might never have found that cloaking device. And that would have really screwed me over. So perhaps the randomness is a little too overpowering.
The difficulty does also seem a little unforgiving. There's a definite sense of being either behind of or ahead of the difficulty curve; the problem is that if you're ahead of the curve, you'll take less damage so will be able to pull further and further ahead of it. If you're behind the curve, you'll take more damage to more systems and lose more crewmembers and use up all your stores, which makes it more and more difficult to get back ahead of the curve.
And, like everyone else says, it would be a real joy to play with the same ship for days or weeks on end. I'm not sure it would be the same game then, of course, but I would definitely be interested in seeing which game it would become.
I absolutely love this game, definitely one of my games of the year so far, but perhaps there's an even better one lurking just beneath the surface?
