While Tim's loving every bit of Far Cry 3, the main complaint to surface about the game so far is that your time in-game is plagued by hints and objective pop-ups that break the immersion (and somewhat poop over the core conceit that it's an open world where you can do whatever you want). Ubisoft have heard the complaints and are working on a patch that will let you completely customise the UI, stripping out the elements you don't want.
Speaking to Kotaku, Ubisoft said:
"Based on feedback from both press and fans, the Far Cry 3 production team is working on a patch that will allow you to toggle most HUD/UI elements based on player preference. The patch will also avoid issues encountered in the .dll hack that might create a mission walkthrough break (missing QTE prompts, critical information, etc;)."
The .dll hack they're talking about is a workaround the community discovered that removes most of the game's HUD elements, giving you a cleaner game. The issue with it, as pointed out in Ubisoft's statement, is that it removes some game-essential on-screen prompts like "HIT 'A' TO DECAPITATE SNAIL".
The patch is currently being worked on, though Ubisoft didn't give a release date. Fingers crossed it will be with us before Christmas.
