There's been a bit of rumbling about gamespot.com having a page with Half Life 2: Episode 3 listed as a featured game of E3 2012. While it really wouldn't make sense for Valve to leak this information out to Gamespot of all places, there's actually a pretty simple reason for this exciting listing.
Still I think that half life 3 is in desperate need of next gen technology.
I would like to see valve integrating gameplay parts of portal into hl3 (practically both games play in the same universe). and for advanced open world portal/physics puzzles the game definitely needs better hardware.
you know, back then in 2003 there was a release date valve just ignored without any further info and suddenly there came the leaked beta. and it was quite bad.
so everybody thought that everything valve has shown until then was fake or at least everything they had programmed.
after the beta disaster and seeing that valve had not really accomplished anything in five years of development expectations for hl2 were quite low.
and suddenly only one year later it got released and had physics and gameplayelements not seen before.
it was just amazing. but this is something you can just understand when you witnessed it back then :D
It's about the awesome story telling. Nowadays most shooters have shitty singleplayer.
Other shooter franchises (there are a lot) don't bother about emotional story telling, and it's just about action and killing.
That gets repetitive (although still fun overall) if you have been a long time gamer.
It's like accusing The Godfather of being popular for the same reason Transformers is.
Just a wonderful game.
I own it x3, but i'll always remember playing it on the ole' Xbox.
Back when Xbox Live was cool, and full of actual 'gamers'.
