Is the announcement going to be that GOG is reviving Uru's online component? ;)

Behold... the HAIR!

This is all too cryptic for me?! *Overload main brain-frame*

If unexcelled IS a clue, then it truly is Zork. That would be... a bit underwhelming, though highly amusing.
Other than that - we know it isn't obvious, so no SS2, P:T or EA...
LucasArts or Sierra ? Possibly...
Would be damn impressive to finally get our hands on the Monkey Island series, now, wouldn't it ?
The problem is - most highly impressive things are also the most predicted and thus - moot.
What was the most awesome and understressed thing we have come up with on these 18 pages ?

We're not talking about a public release here. EA would give GOG the code to work with. Or do the work themselves. Whichever. But the code wouldn't be released to the public.
I don't think the source (and subsequently clean) code was available in that case. It would certainly explain why the publishers did nothing about it themselves. There's still an 'Online Activation' graphic in the menu that the GOG guys say they can't remove. Which added to the many weeks it was in the 'Coming Soon' list gives you some idea of how much work they put into that one.
I'd actually say that older Windows games are harder to get working than DOS games. Admittedly, DOSbox makes that all the more true. But even without that benefit there's still the matter of all the legacy standards that old Windows games adhere to. Comparatively DOS games are much simpler.
For starters there's a driver issue. Newer GPU drivers only go back so far (I think back as far as 7 or 8). Some games subsequently are rendered incompatible. Not because of Direct X's own incompatibility with previous versions, but simply because ATI & Nvidia drop support for those early versions. Sometimes that's not a problem. Other times it kills all possibility of the game working.
Secondly there's the issue of games not supporting 64bit OS natively. Which certainly proves problematic with the crappy XP 64, even if Win7 64 is much more 32bit compatible it's still no guarantee that very old games are going to work.

Zork is even older than me. Not by much, but still. It would turn GOG into GAG - Good Antique Games. I don't like the sound of GAG. :P

Although Mikee said it's not the most obvious, he also said it's the biggest announcement since the opening of the site.
[funny idea]
What we're waiting for will be an interview with Ralckk, who is THE unexcelled GOG user (well, considering rep points, at least).
[/funny idea]
Anyway, I encourage everyone to take up my stoic stance towards this "big announcement". I don't really feel "OMG how much till Thursday???" about it, and I'll take whatever it is with either a "So, it's ***? Oh, cool." or "Well, it doesn't really affect me, but I'm sure some users will appreciate this." sort of thought.
However, I'll be sure to be here quite a bit earlier... Guess the servers will be a bit overwhelmed. ;-) (Hey, staff, didya hear this? I hope you prepare with some extra-durable, extra-spacious servers!)

Jedi light saber like background ? LucasArt !

Too bad, the community would benefit from that.;)
Now i see.;)
Simpler in writing? Or as a structure?
Considering that You didn't have stuff like DX, and You had to work on a finite amount of memoty, DOS games were "tricky" to write, and in some such cases, tricky to run.;)
Yes, i have noticed that graphic card manufacturers don't give a crap about backward compatibility, and from what i've tested, thats about the only thing that makes Dungeon Keeper unplayable on my x64 system. I know what You're talking about.
The older DXes aren't yet supported by VMs, and i'm afraid that VM makers are not really interested in them, But since VirtualBox uses D3D from Wine3D, there's a chance for older DX to be supported as soon as they do their magic.;)
The problem would most likely lie in the 16 bit nature of some older programs, which are incompatible with the 64bit architecture. Or sth like that. Emulators will save us.;)
A Necrogaming Gem! ;>

Wait, wait, wait... That's some odd wording right there.
Pain ? Action ?
Am I the only one having a sort of an epiphany ? Because if I'm NOT... It's going to be my favourite game of all time ^^' !
OK - get this - "unexcelled" = "max" xD ! It all fits...

Well, if we were into dissecting each word and examining it, then:
1. "to be honest", and Honesty is a Virtue,
2. "..The counter I mentioned just BTW (but rest not - read carefully;)" sounds a bit weird on the grammar side.. But rest not.. Avatar.
I guess we could all read something different from the clues given.;>

For my own egocentric pleasure I hope it's EA ..
I want to play Bioforge , Syndicate (1 and 2), Dungeon Keeper (1 and 2), Crusader (1 and 2), etc.

Oh my, that is an interesting prospect. Max Payne could mean Gathering of Developers is coming... oh wait, most of the members of GoD are already here... hmmm, does that make it more likely or less?

and Take Two was mentioned in earlier posts... ;)
