Gears of War 2 - Release Date 11/7/2008
Left 4 Dead (1) - Release Date 11/18/2008
How interesting. Valve managed to originally "relabel" Epic's ideas in only 11 days. What wondrous logic you have. Or are you claiming that Left 4 Dead 2 is the relabel of Horde mode, when clearly it would be a relabel of L4D, which could not possibly have been a relabel of Horde based on the time difference.
Oh, wait, development of L4D started in 2005, well before Gears 1 was released, let alone Horde mode for Gears 2 was announced. Interesting. So, if anything, it could be more easily argued that Horde was the relabel of L4D, not the other way around.
How interesting...
You don't like the game. We get it. So, why exactly are you trolling this thread?[/QUOTE]
If by development of L4D started in 2005, you mean that a whole bunch of guys sat around a desk and said let's make a game about zombies, then yes, that's when development started. As it neared the point where Valve realized they actually had to make a game out of the nothing they had, they snatched onto the idea of Horde, which Epic announced years before Gears 2 came out, and decided to make it a game. Here's how it went:
Valve employee #1: Let's make a game about zombies!
Valve employee #2: Great!
Years later...
Valve employee #2:

! We haven't done any actual work
Valve employee #1: Looky here! There's an article on a new game mode. We could just take that, and not have to come up with a story or anything! All we need is a glorified random engine and people will buy it because we're Valve.
Valve employee #2: Brilliant!
And the standard for narrative in videogames once again slid far, far down.
