Not to sound overly pessimistic, but I wouldn't get your hopes up on this one. From the first post I immediately got the impression that while tictac may have great ambitions, nothing of his plan seems concrete. Personally I've found that in software development exactly that, a concrete plan, will get things done ("I want this location where the character will be able to do this and that and if you do he can say this and that", etc.). Without it you can discuss for hours about features and not get anywhere.
So, my advice to tictac (and whoever might be working with him) is this: start small, VERY small, in fact, cut down your entire idea to its basics and make that concrete (what can happen, which options do we give the user, etc.). I can assure you that even for something that seems small and won't produce the most exciting game, the time needed to actually implement it and get it working is way more than you'd expect. But in the process you'll hopefully learn about how to work on a project like this effectively.
Given the nature of the idea I'd say that extending on such a basic game would be a piece of cake and won't require many things to be done over. And this would be the point where things get exciting, gameplay-wise.
The reason why I suggest a strategy like this is because while having ambition is great, it usually doesn't create games. In fact, I've found that ambition can die out very quickly if you don't get results. On the other hand, getting results is a great motivator. And that's what I believe you should aim for.
Please note that all of the above is just my opinion, I'm not telling anyone what to do or that tictac is giving us empty promises. For the sake of the community I sincerely hope that my views are wrong and that tictac will be showing us a game in the coming weeks.
