I agree with the ones who say that the first l4d is not that great game.
The "director" simply cannot save this game, when you have to do the same map over and over again.
It's only 4 campaigns, hardly 2 hours each. You start in the same place, end in the same place.
It's not like there is much more to explore or discover. It's only about hoping to find someone good to play with and go from A to B.
I was very disappointed the first time I got to the end of it (it took a bit longer only 'cause of poor on-line players).
I played oblivion for more than 100 hours. I still play and enjoy very much Battlefield Bad Company on-line (every battle is different with up to 24 players on line), but really I can't play more than six times the same maps.
Four campaigns are barely a demo!
There's no real single player mode. And it's all about doing the same thing in the same location over and over again.
I don't care about fan made content, I have l4d for xbox 360, not for pc. When will I ever see a new campaign or new monsters or new weapons? Besides that, I want the quality the producer can give! I did not buy the game only to wait (and hope) that someone somewhere can get something good out of it! I bought it because i thought that Valve did (or could do) something good.
Moreover, as somebody said before, there's no real innovation in l4d2. Melee weapons make things only more complicated and frustrating, with people that will surely get caught in friendly fire (it already happens way too often...).
Even if (as they say) this time the campaigns will be more linked together, it will not add much more to this game (the graphics are practically the same, if not worse, music are worse -darn banjos- the characters make no difference at all since they have no story or peculiarity at all even in the first one).
They would have done better making only one good game one year later. L4d1 really looks like a beta, especially if compared to a new game.
So, bottom line.
For me, it's not as much about the new game, but about the all thing.
I paid 50? (yes, I'm Italian if you didn't get it already) the game which is far above its real value.
Since it seems that there is no real improvement in l4d2 I'm not going to buy it.
They didn't make a new game, they only made slight changes in the old one. It looks very much the same (if not worse).
I repeat, if they made something new so soon, it would be a great thing. Since it looks like they did not, is bad either for the first l4d or the last.
And it's not as much as boycotting, as about constructive criticism.
I sincerely apologize for any mistake I made writing this post, as I said I'm italian (if that could be an excuse
).
