The day GOG gets TIE Fighter is the day my brain explodes with joy
This might be a bad thing since I won't be able to purchase it

OMG If Tie Fighter is ever released to run on modern PCs I will have to find my old CH Flightstick and lock the doors. It will be a truly jizz-tastic day.
Although I'm glad that LA is taking more notice of their older games, I'm still doubtful that Tie fighter will make it because they have rehashed their adventure games a few times and nothing,nada, zilch for Tie Fighter.

But the re-hashing of TIE Fighter is in line with their endless milking of star wars so it might still happen.
I caved and decided to buy Republic Commando on Steam, shall see how much I regret it in the morning

They put Starfigher up on Steam...the indisputably unawesome Star Wars flight "sim", so I'm leaning on anything can happen for the moment.

That makes two of us then.

I'm not buying any of the LA games on Steam. I will wait for them to show on GOG. I can't help it, I like the "I own the game" feeling and the goodies GOG usually offers with every game.

I'm looking forward to seeing what else turns up. Especially if that includes Grim Fandango. Hell yeah! It has to! If they do a weekend deal on SCUMM games, then my love for Lucasarts will be renewed.
GOG can still trump this by snagging Planescape though. They've had Fallout from the same developer and publisher, right from the start. So I don't see why it's out of the question (although there may be a licensing issue).

And this backup 100% useless because the game is unplayable unless you reactivate it online, the only use of Steam "backup" is in case you have low/limited bandwith and don't want to have to redownload your game.
Well that sucks, I was really hopping to have those games released on GoG instead...
And worse, Steam version are not even compatible with Scumm so it's not even possible to remove the DRM...bleh... I'll definetly pass, well it's not like I don't already own most Lucasart adventure games.

Which is the same purpose for backing up a GOG download (i.e. so you don't have to re-download it).
The Steam backup is only useless if A) you have no internet connection (so why do you have Steam?) and B) you don't like Steam and are looking for yet another reason to hate it. I find the backup to be extremely useful for moving my Steam install to multiple computers, saving my GIGs of Steam files when I do an OS re-install and running Steam game on Linux. I've got everything backed up to an external hard drive (the same that stores my GOG files) and I have Steam running on no less than 4 different computers in my house, but I've only actually downloaded any of the games once, thanks to its backup ability. This is extremely useful in my book.

No, it's also useless if you are looking for a way to do a real backup which is not dependant from Steam and it's good will or a working Internet connection to run.
That's the reason why I backup my GoG games (and the few DRM-free Impulse one) so that I have copy that will work in x/y years, no matter what happens to the shop where I bought them.

But what if you want to play a game on a Notebook/Netbook where there is no internet connection? For example, you are on a holiday trip and you want to play something, you should be able to run your game everywhere. And some internet providers (like Polish biggest ISP TP S.A.) give you a rather crappy Internet connection, so often/rarely you can't play Steam games at all. Most time I can play my Steam games, but sometimes I have no connection for hours. Maybe it sounds silly, but if I want to play a game, I should be able to do so.

You know that if you save your password in the steam client you can play the games in off-line mode? You just have to have logged into steam online once before to verify the account. From that point forward you never have to connect to steam unless you want/need to patch the game, or play online/multiplayer.

Tell us if the game runs well, please, I really liked this title. Maybe not the best FPS of all time, but it was an excitingly dark and more mature Star Wars title. And the squad members have so good lines.
Talking about Star Wars titles, here are the ones I'd really like to see re-released:
- Dark Forces (my fav)
- Jedi Knight: Dark Forces II
- all the X-Wing and TIE Fighter series
- the first Racer
- Shadows of the Empire

You are not dependent on Steam's "good will", Steam is dependent on our money, so if we paid for the service, they will provide it. It is business relationship, plain and simple; good will never even enters into the picture. In the nearly 6 years that Steam has been around and I've been using it, it has never... NEVER... failed me, so I have absolutely no reason to think it ever will at this point. Besides, a game being tied to Steam is really no different than a game being tied to a copy protected physical piece of media. Sure, you can create a backup of physical media, but you can't really use it without still having the original, just like I can't really use my Steam backups without Steam. I fail to see why this is really a problem for some people.
As for the internet connection thing, I hate to be callous, but that is really your responsibility, not Valve or Steam's. If you've got a crappy connection, do something about it. If you can't, well, then you should have thought about that before you chose to use Steam (or like Sielle said, take advantage of offline mode). We are talking about gaming here, its not like have to or need to do it, it is a luxury. If you do not have the means or ability to take advantage of that particular luxury, do something else instead.
As has been stated by Valve, if Steam ever went under, they would provide the means to run the games without Steam, not that I think we really have to worry about that happening anytime soon. Steam is to digital game distribution what iTunes is to digital music distribution... the biggest there is, showing no signs of failing, only continual growth. I'm sure that growth will taper off at some point, but the fact is, right now Steam is too huge and too stable to collapse anytime soon and even if it were to collapse, we really have nothing to worry about (see bansama's post above for more on that).

Well, maybe Steam never failed you, but they failed all Europeans by increasing prices of games by 42% (and sometimes even more).
According to Steam 1$ equals 1€ . Did you know than in Europe most newly released games on Steam cost insane 70$? (50€).
There is a huge thread on Steam forum - http://forums.steampowered.com/forums/showthread.php?t=770231 - which is regularly censored). It has 6000 posts and 600000 views (no typo) and Steam completely ignored all complaints for the past 7 months. If they can do that, they can just as well cut you off form all your games.
