Sounds very ambitious. The continents each having their own giant sized map sounds great. Enjoy the PAX show and I can imagine you'll have a lot more progress by next year to hopefully enter this game.
I won't be going to PAX since I won't be able to make a playable demo in time to enter in January, though that would be awesome. I would say that both the editor and the game itself are huge projects in scope, I started working on the concept of the game in September 2012, had to learn how to program and and all that jazz before I really understood how to go about it, so I feel that I am doing okay in terms of progress really. I could have made many smaller, simpler games by now, yet I knew the weight of what I was getting into when I first began and always intended it to be truly epic in almost every detail, but also unfortunately with that also comes at the price of a lot of work. And this definitely includes the continents and the detail invested in each one. They will probably each have anywhere from 3-8 towns with anywhere from 20-50 NPCs per town.
By Winter 2015, I aim to have a semi-feature complete playable demo (I will have to in order to qualify to enter the PAX expo) so hopefully you are all still interested in playing it by then haha. As for more updates, all it would really be is something like this...
11.9
Worked on code for about 2 hours
11.10
Worked on code for about 2 hours.
Had some problems with *some random issue*, finally figured it out.
...and so on. I COULD do that, but I feel that only truly relevant progress should be shared. Anything else may be annoying or unnecessary, also I don't want to spoil the actual experience of playing the game for anyone. For the time being, I am postponing any artistic/ design development until the tile/ map editor is in at least a semi-functional state, so there really are no exciting pictures or video that I could share but since there is an interest in it, I will release the .ged for the current build of the tile editor here in this topic (keep in mind, a lot of work yet to do, a lot of testing and running different bits of code and I make some crazy comments to myself sometimes in code haha) So, here is that for anyone interested in checking it out. It is over 2mb so I had to upload to Mediafire.
http://www.mediafire.com/download/icv79w8vpzzdmft/NewEditor.zipWhen I release the fully-functional version of the it, I will post it as it's own topic here on the forums. Most likely in many categories (Game Development, Advanced Topics, Game Resources, General, etc) which will hopefully be a valuable resource for the GE community to learn from and utilize. In its current state, I would say it is about %25-30 done. I am just adding feature by feature from a list I created after I designed the program on paper. Once it has reached %50 the other %50 should be relatively simple actually but it will probably still be a month or two until it's functional, maybe a little more. If you have any questions about how it works, I'll try to answer them but there is a lot going on so some parts are a bit difficult to explain. Basically you have to input a map width and height size, it automatically chooses tiles of size 128x128 for now but the final version will allow 32x32, 64x64, 128x128, and 256x256. Other sizes or even shapes could be added in later if anyone had the initiative to work on the code for it. I have created maps of up to 750x750 on my computer with no problems, and could probably do larger ones, but it may take a moment to generate. None of the extra features such as the Show/Hide commands in the map size prompt are available yet either I should mention. After the map has been generated, if you move the mouse up to the top of the screen, the main menu will show up and you can go into the tile menu, and click on the choose new tile set button, and it automatically chooses a test animation. I am still working on some features relating to the tiles / tile placement.
But of course, if doing that would steal too much time from your actual working time with the game, I understand and encourage you to concentrate on what's most important, getting the game done.
