OK, apparently I have to put a screenshot here too:
And tell you a bit about the game:
Its an open world RPG. You move around some big strategic maps, and fight turn base battles on a tactical map. Explore dungeons, do missions...
Full details in Steam, above!
I also especially wanted to thank AdamBiser for his amazing steam plugin.
And... the only extremely complicated thing I coded in TBotG was "Timely pathfinding on a big map"
You would not believe how many papers I read on this to get to something I was happy with. If anyone needs any help on this, I'll be more than happy to try and help out.
