Seriously. I just checked both HUBs and there's like 10.000 threads about L4DvsL4D2.
-Player 1: OUHMAYGAWD L4D is so much better than L4D2.
-Player 2: NOWAY man L4D2 kicks L4D ♥♥♥.
-Player 3: Pff n00bs CoD is the best. Yo mom. Hahaha.
-mlpPlayer 4: I like ponies :3.
Both games have pros and cons. Yes I hate Ellis and Rochelle but in L4D there's like what... 5 weapons to choose from? L4D have better post apocalyptic feeling but L4D2 have melee weapons. L4D have better maps but L4D2 have more special infected(and L4D maps)
I love both. Both are great games. There's no reason to hate someone else just because he/she likes L4D/L4D2 more.
So yeah, stop acting like a bunch of kids, move on, play your L4D/L4D2 and stop posting same stupid threads. It's that simple.
