Addon campaigns that provide significantly more gameplay than the stock ones? Some of the L4D1 campaigns are very high quality and are worth downloading and playing. Once we get the L4D2 tools it’s going to be even better since mod developers will now have the ability to change the entire game, basically. We rarely get that with any other PC games and are stuck with content that the developers or other parties produce officially. Personally this is the reason I purchased both games; for the toolset support and community involvement that you rarely see in any other titles.
And you can’t do this in L4D? You often have to since the SI spawn in different locations and at different times. It’s not a story-based game but it would be just as bad if they portrayed an epic story arc through L4D; its just not that kind of series. They play it out in smaller more subtle ways.
I haven’t played MW1 on PC but MW2 is pretty shitty about a lot of this stuff. It has lots of game modes but is very restrictive about them, and most of them are more frustrating than fun, especially modes like Sabotage which can’t be played with hardcore rules and are prime for people camping as a legitimate strategy which gets boring and frustrating fast. The class customization is nice, but once you get the unlocks I see no drive to keep playing if you don’t like mindless DM or TDM games which are basically the meat and bones of MW2 MP. Unless you want to go through prestige mode which is just a cheap trick to extend replay time IMO.
Actually the total is closer to 18 maps…each campaign is 4 or 5 levels. Are you aware there are multiple gameplay modes as well in L4D/2?
Edit: I’m not quite disagreeing with you that it is the same every time; I can only handle L4D games in moderate doses. But playing them with friends or even alone is a great experience and I can’t really say that I’ve felt that from many computer games recently.
