Zeraaan! I went on your site a few days ago to take a gander at your work, looks like its going well.
What completion stage you are in? Say, in %?
What about the code? Codexx teached me that most coders today would be thrown out on their ass in the good ye olde times, because it seems pretty mmuch everything today is unoptimised as fuck. You want a infinite map, right? You're going to need very good optimised code, bro.
So, you manage to put in multiple polities in one planet? I have sum wacky ideas for it in the future... anyone up for playing "Clash of Cultures, a Codexian 4X" over the internet? Imagine multiple countries expanding through and trying to escape population earth by going to space, fighting there and then meeting and dealing with aliens (divided AND undivided), berserker probes and whatnot. I would eagerly volunteer for writting the lore, Alpha Centauri-style. IMHO Space 4X always lacked a good SMAC-style lore to give some extra atmosphere.
