Dug through my records for some clarification on this.
The plan initially was to start on the first pack around July 7. But while I technically did, work was extremely slow through most of July due to me having to spend a lot of time on unrelated IRL issues. So yes, due to this delay the effective time since the July start date for the first pack will probably be four months, not three. Three months of solid work, but with a month "wasted" on non-game-related stuff. I'm currently targeting the end of October as stated. I've indicated the initial slowdown in various posts, but hopefully this will clarify the current state of things.
Note that while I take timeliness seriously, dates WILL shift, which is one of the reasons I rarely give especially defined ones. Sometimes up, sometimes down. Sometimes I'll over or underestimate what it takes to get something done, and sometimes, like here, unexpected things will come up. The important thing to me, and hopefully to the fans, is that I'm putting in as much time and effort as is possible, and planning in a way that's practical and doesn't get bogged down in idealism or perfection.
I think the timelines for GT are a perfect example of what to expect. I dramatically missed my first deadline, because I underestimated the scope of what I was doing. But I delivered within a month of the second, which is pretty good for a 13 month project.
