Looks fantastic, especially considering that YouTube's compression apparently did some bad things to the visual appearance.
 http://forums.blackmesasource.com/showthread.php?t=12124: The compression YouTube applies has blurred and darkened everything, even at 720p settings...I've got the original video at 1080p, and everything looks fine.
What's funny is that now Team Fortress 2 is free to play, and counts as a Source engine game, so you don't have to pay Valve any money to play Black Mesa. Of course, now you have Steam with all its sales installed, and the likelihood of you wanting to play it without having purchased any of their other games is pretty small...
If they tried to sell it for profit I'd imagine there would be some very pissed Valve lawyer breaking down doors though - because I don't think its officially & legally blessed.
Have (immature) fun with their 404 page:
The soundtrack is released ahead of time for your pleasure:
This is a mod I have been waiting for a loooong time. Can't wait to dust off my fps skills while enjoying the game.
A long time in the making, I hope the devs are proud of their work and that their work is going to give them pride.
Citation needed. Load times aside, Half-Life 2 was a spectacular game, and one of the best-reviewed games of all time. Metacritic's score for it was a 96 with 81 positive reviews: http://www.metacritic.com/game/pc/half-life-2
edit: OHHHHHHHH. My bad. Thanks for pointing out that they were referring to Half-Life: Source.
Additionally in Source there are (or at least were, I played it years ago) several places where there are graphical glitches. Textures missing from certain surfaces and whatnot. Each of those little things really built up a general feeling of "they did not really care about this".
>This will include our re-envisioning of Half-Life all the way up to Lambda Core. We believe this is a great way to provide a complete-feeling 8-10 hour experience with a solid ending, make our fans happy and help us make the best overall game possible.
>We are still working hard on Xen and BMDM, but instead of making you wait we are giving you Black Mesa as soon as it's ready!
It's been so long since EP2 was released and I'm sure the new game will feature vastly updated graphics as well as some new gameplay mechanic (like that gravity gun did to HL2).
Hopefully I can recommend this to a friend who hasn't played HL at all. He isn't really into games but recently bought a laptop with a decent graphics chip. I told him that if you are only going to try one PC game then it should be HL but the graphics of the original look very dated now and don't work well on 16:9 and jumping straight to HL2 may be a little confusing without understanding the context.
This mod aims at making the experience have the same feeling, while updating the gameplay, graphics and architecture of the environments to more closely match the original designs that had to be scaled back because of performance.
The original half-life is very dated when it comes to graphics, and the pathing of the AI is sometimes hilariously bad, but other than that it's still extremely fun to play and gets a decent little story out of the tiny amount of time actually spent on narrative.
This is the real genius of half-life: it doesn't go down the awful Hideo Kojima route of 45 minute "LOL HERE'S THE STORY!" cutscenes, rather the story is simply there in the game, it happens around you. It is possible to pretend you're playing quake and blast through without taking any notice of it, and it's also possible to play it a bit more slowly, and upon consideration the story is actually quite deep.
