A sequel so close to the original - (Left 4 Dead launced last November) seems to have the fans of the title confused. Some, who have spent tons of hours in zombie guts glee are extactic that the new game, with new features and improvements, is coming out so quickly.
Others feel ripped off - and that in typical Valve style they would be playing free upgrades and mission packs for a long time from now (a la TF2).
Read the comments in this blog announcement to see the ruckous.
I can understand the fret from an economics point of view, but the fandom in me from a title I logged 100 hours playing for the box (through the single player, co-op, co-op versus and recently free released survival mode) and loved every minute. A game with set play, limited levels, and replayability isn't going to hold me much longer than that. I am ready for something new.
So it comes as no suprise, that I am pretty excited about the announcement.
In Valve's defence (if it's needed) or additional cheering (which camp are you in this announcement?) they haven't said the pricing structure, future support for L4D1, or anything of that nature. One would suppose that the majority of the fan base of L4D1 will pick up the new title, leaving less games for people who stick with L4D1. You could also make the argument that by next November, a lot of people will be tired of the original title and ready for new anyway.
Will be interesting to see how it all pans out. Whatever Valve has touched lately turns to gold - hopefully that translates into gold zombies, and not upset L4D1 fans.
