all games are not created equal

As much as MK has the new characters of DC [Joker, Batman, Wonder Woman, Superman etc.] added to the list of original characters [Scorpion, Sub-Zero, Sonya, Liu Kang, Raiden etc.] the game-play was the same.

The story line was interesting due to the question of  "How the HELL are we gonna blend these two worlds together?".

Left 4 Dead I found that it was more challenging and intriguing to me even though it was the typical "shoot-em-up" Zombie game. I liked the idea of the Special Infected [Smokers, Boomers, Hunters, Witches] especially the Witches. The idea is NOT to kill her.

Hmmm, interesting. . .

I also enjoy the fact that this not just a single-player game and takes a group effort to beat it. I found that being the infected was REALLY cool and fun.

Anyway, to make a long story short. I enjoy Left 4 Dead better than Mortal Kombat vs. DC Universe.
