Valve really did strike gold with Left 4 Dead. In case you do not know, Left 4 Dead is a 34 player co-op game that sees a team of people need to survive a zombie outbreak. The game places a very heavy emphasis on teamwork and at the time, it was one of the most fun games to play with your buddies online.
The first Left 4 Dead was released in 2008, Left 4 Dead 2 followed a year later and then… nothing. The games sold well enough were very well received, but for some reason Valve, has decided against making a third game.
Left 4 Dead came and went just before the huge streaming rage took over and everyone loved to watch other people play games and play together online. I think that if Left 4 Dead were to be released now it would be huge in both people wanting to play it and also watch others play it, I also feel that a Left 4 Dead 3 would be popular in the world of ESports!
A huge part of what made Left 4 Dead so much fun was the director AI. This made it so that no two games were ever the same. One time you could play a scenario and the map would have very few special zombies, next time it could have a few bosses like the Tank and the Witch… man, I hated the Witch! She was creepy and hard as nails to deal with!
Left 4 Dead is a game that requires teamwork. You can try and survive on your own, but you will not get far. I have fond memories of playing with my friends online and coming up with a plan to get from point a to point b and survive all of the zombies. 99/100 something would go wrong, all hell would break loose and we would have to just do whatever we could to survive. Left 4 Dead walked that perfect balance of being a really tense game, but at the same time, it was really fun. You never wanted to leave a buddy either as you needed all four people in your squad to survive as that made it easier.
I really do feel that a Left 4 Dead 3 would be a huge hit and as the first two games in the series were Xbox exclusives, I think it would be a huge coup if Microsoft could get that kind of exclusivity once again.
