And I know that....

I personally think the hate behind FO3 are the generic RPG elements which have little to no impact on your character. You can reach the max level20 (or 30 with Broken Steel) less then halfway into the Story and by that time it's easy to have maxed skills and maxed stats and be more or less a God in the game. It doesn't help that the game is massively unstable and crashes at the worst times (when saving, middle of firefights, opening the pipboy). Be as that may I am addicted to FO3 and am still playing it. I just wish they forgone the name Fallout and released it as a new IP.

Could be. I never really understood some people's intense dislike of Fallout 3, myself. Sure, it played nothing like Fallout 1 or 2, but... and I realize this sounds somewhat counterintuitive... the gameplay doesn't completely make a game what it is. For me, the most important parts of the Fallout franchise were things like the setting. Getting the setting right... capturing the dark, bleak humor of the Fallout 'verse... giving the player the feeling that they really were wandering a gritty, almost empty post-apocalyptic wasteland... these were the most important parts of Fallout. If you didn't have these things, even if the combat engine and what-not was exactly the same as Fallout 1 and 2, it still wouldn't be a Fallout game. Likewise, in my view, if you had the aforementioned stuff, you could have a completely different engine under the hood, and it would still be Fallout to me.
Sure, Fallout 3 was basically Oblivion with a different setting. But it was Oblivion in the Fallout setting. Hence, it -was- a Fallout game to me, and I loved it. And I really need to get the DLC for it and go through it, because Dadgum it, my Vaultie wants her spiffy Gauss rifle! :D

Bioware stated on their forum the PC version would get the new DLC as well, along with a patch from Bioware itself to fix the lingering texture issues in the PC version left by the contractor who ported the game.
I personally cannot wait... Mass Effect was one of my favorite games of last year.

Perhaps I'm mistaken, but I seem to remember early in the development cycle (after it was announced) that the devs kept saying not to worry that it would also be coming out on the PC at the same time. Then again I could be wrong, it wouldn't be the first time my memory has failed me.
The point of BDtS being thrown in because it was out before PC version was released is still valid.

I believe Coelocanth is right in that it was originally intended to be an X-Box only title. PC users got lucky in that they eventually did get a port of the game. It's definitely one of -my- favorites, and I don't own an X-Box, so I'm certainly happy we PC users got to play it.
I'm looking forward to the DLC. It'll give me a chance to fire up my character again, maybe gain some more levels in preparation for ME2.

...it's just too bad that the PC version is full of bugs. Bioware promised a patch some 6 months ago as 'coming soon' and it's still not out yet. I can't play the game for more than 5 minutes without hitting a general protection fault.

Yeah, I recall being very disappointed to find out it was an XBOX exclusive (since I love BioWare's games and don't own an XBOX). And they denied any PC port was even a possibility right up until the day it was finally announced officially.
Yes, I believe that's the reason it was free for PC.
