Alright, here's a little suggestion I want to make to alter the requirements for the "Good Guy Nick" achievement for Left 4 Dead 2.
As a passionate gamer, I am always looking to complete a game and experience everything it offers the player. When I finished all achievements for Left 4 Dead 2, I was simply playing for fun after that. Until I had all achievments though, I was more or less an achievement hunter.
Call me whatever you want, and yes I know that I don't get anything for completing the achievements, but now that they are here, I want to get 'em all. Easy as that.
The only problem I have is this:http://cloud-4.steampowered.com/ugc/487811888482495453/5B90172A65C345C24D9D510B2162E732CA7FC9AD/
Damn right, the "Good Guy Nick" achievement is the only achievement left out of all 70. You can obtain this achievement only if you own the game and play any campaign from start to finish together with a player who doesn't own the game, but plays it on an occasional "free to play" weekend. Now that Left 4 Dead 2 is totally free for all those guys who downloaded and added it to their library during this holiday, I fear that this gift will dramatically decrease the number of people who would like to "try" Left 4 Dead 2 before purchasing it if there will ever be another free to play weekend, making it practically impossible for us to get the "Good Guy Nick" achievement.
Now here's my suggestion to make a gift to those players who purchased Left 4 Dead 2 a long time ago as well: Make the players who got this game for free count to the "free to play" people, which would mean we could get this achievement on ANY upcoming weekend if we are playing together with someone who got the game for free from Valve this Christmas.
I know this is somewhat selfish, but I can't help myself looking every week into the forums to see if there's a free to play weekend for Left 4 Dead 2 coming up so I can finally get this achievement. To be honest, locking the achievement to a specific (and very short!) timeframe is just a horrible idea which should never again be used for future achievements.
