Big Download doesn't like to editorialize in news stories but it's pretty clear that a lot of Left 4 Dead fans are very upset about Valve's surprise reveal during E3 2009 about Left 4 Dead 2. The game's new official message boards are full of comments saying basically, "Valve's releasing a sequel too quickly for us; this should be a free content update for the original game." As Valve's Doug Lombardi told BD during their play time with a build of the game this past week, "This is something new for us." By "new" he meant that this time Valve is not waiting for years to release a commercial follow-up to one of their major games. (Half-Life 2: Episode 3, hello?)
Many fans are not happy because they feel the original game (still a top 10 best selling PC game in retail stores months after release) will be forgotten now with Left 4 Dead 2's announcement. Again, Lombardi assured them at E3 that is not the case, promising that the first game will still be getting updates and new content (although exactly what they have planned is still a mystery). Lombardi also told Rock Paper Shotgun that any maps made for Left 4 Dead's SDK will work for Left 4 Dead 2.
