I've checked out your most recent guides for Infinite and Crysis 3, and they're solid work. So if you want to take full control of the guide, don't let me deter you from doing so!
However I do plan on starting the game up early Wednesday morning when it's available on the Marketplace, so perhaps if we work on it together, I can write up the information for the achievements that don't relate to collectibles. I can then send it your way later in the afternoon if you want to post the guide, or begin writing up the guide myself while you work on the collectible potion.
Or alternatively, if you want to keep the guide consistent by writing it up yourself, I could always do the roadmap. Let me know what you think!
