Well, it wasn't all bad. Just bad in the areas that mattered.
Universal ammo - Retarded.
Much smaller areas than the original - Retarded Engine.
Stealth - Retarded.
Most of the guns - Retarded.
Main Plot - Retarded.
The new bio-mod system - Not Retarded.
Being able to choose gender - Not important, really, but nice to have it.
I agree with the first half. But I think the bio-mods were stupid because they stripped out about half of the options that you had in DX1. Less is not always a better design choice.
And as for gender, it didn't matter. At all.
I thought agumentations were incredibly outdated by the time of DX1, and that there was only one obsolte agumented freak, who was also a conspiracy theory nut (his conspiracies turn out to be right in DX2).
So, no, it doesn't matter how cool the hero is in DX3, by the time DX1 comes around, he's already obsolote.
Being aware of your oncoming obsolescence could be an interesting story component. Not every character has to be a 100% perfect ultimate badass. I think that sort of character is actually really boring and pointless. Why even bother.
Second, the nano-mods may have been a better choice because the mech-mods required more maintenance and installation was more dangerous. Rejection would be an issue. But certainly it would be a matter of better tech coming along. So even if they had stayed with mech-mods, the new kid would have better gear than the old fart. But it's possible that the new kid with nano-mods is cheaper to produce and upgrade, while the old fart with mech-mods is a tough old nut who could take the kid out any day.
The universal ammo system is neat. It lets you worry less about ammo, though it broke immersion for me, as I couldnt believe in universal ammo.
Uni-Ammo
is simpler. But there is a point below which more simplicity is a bad thing. When someone tells you they preferred different ammo types, they are saying they want a more complex game. When you say you want Uni-Ammo, you want a very simple game. Different player demands.
That said, don't think about Uni-Ammo too much because it actually is a pretty retarded concept. And I'm in the camp that feels it's better to have 9 different types of ammo in the game for 20 different guns.

Finally, I don't care about DX3. If it's DRM-free, and I like what I see in the reviews, I'll wait until it hits the bargain shelves for $5. But I'm through with buying new and/or horrible games. DX2 was so bad, just so absolutely disappointing, it actually pushed me out of the video games market as a buyer.
