On the other hand: I recently tried playing one of the Freespace games for the first time after purchasing it from GOG.com, and I couldn't hit a damn thing using the analog sticks on a PSX-style Logitech USB gamepad/joystick. I tried the mouse and found it had great aiming accuracy, but crappy turning control. I haven't been able to motivate myself to try again since :(
Yeah... With the exception of games that are specifically written for mouse control (like Freelancer), or games where weapons auto-lock to some degree, 1st-person space shooters pretty much require joysticks to be playable. It's usually not the fault of the programmers, just the nature of the gameplay. :P
I'm surprised that you didn't talk about DN2 stealing graphics from Turrican
Without going into a huge rant about this (because I could) and speaking not just as a game reviewer but also as a game designer, I try not to focus on these sorts of things when I do my reviews because often when people use a couple or three tid-bits like this from other games directly in their own games, while the rest of the game is completely original, it's usually because they really like the games those elements came from.
Believe it or not, a lot of people won't play certain games simply because of the tiniest similarities to other games, even if they're not directly stealing elements, and some hobbyist developers who are just making games for fun don't have the resources to make certain elements themselves. I used to BE one of those hobbyist developers when I was a teenager and thus I don't like to draw attention to these things unless it's blatantly obvious.
