Landmark developer roundtable touches upon the toolset, tweak mode - video
Landmark testers were recently polled on which tools in the sandbox title needed more "usability iteration." According to the questionnaire, Sony Online Entertainment found that not one tool needed the most attention. Not to say players didn't offer any suggestions, mind, just there wasn't any one tool which was focused upon. Other topics in the video posted below, address changes to how tweak mode will handle large objects being pasted, and how the studio was hesitant to add specialized tools due to "microvoxels." You can hear all about it below. Thanks, Massively.
