thanks for the info and the depth of your replies. All the talk of simulations peaks my interest, personally I'd love to see a game like this married to an Achron-style meta-time so that you could play around with the history and future of a universe... 6hs seems a little short to me but I suppose I'm closer to the player who strives towards but never actually achieves capturing 100/100 planets in AI War, millions of sims in a simcity region or a giant 50+ sprawling demonic city in Civ4 (/fall from heaven/MoM modmod). I like the idea of replaying the world but it isn't quite the same as staying with your fleet in your world, tending fragile alliances and fighting tooth and nail for some goal you set yourself.
With those similar players in mind - Do you have any plans for an epic or marathon setting that, for example, delays the invention of game-ending techs/buildings/events 2x, 3x or more times. (Either directly or by reducing income/research per population)
Second question, have you thought about making achievements a bigger deal?
I've seen them in AI war and Bionic dues (only bought it yesterday, but picked up a few achievements already for one normal game completed). I think they're a useful, cheap, extremely simple but powerful tool to encourage and reward otherwise merely self-imposed challenges and to guide players into new and unusual ways of playing. (not merely a mark to record if you've completed the game.) Peter from Gameinabottle working on gemcraft 2 had a post about his planned use of achievements and use in indy games (
http://gameinabottle.com/blog/2013/01/gc2cs-achievements/) - basically showing a small subsection only and using a script to create simple icons for them.
so e.g. Pacifist run - never fire a shot in anger, is it really possible? Blockade runner, Medicine man, Typhoid Mary, My friend has a moon and he likes to play pool with it, Pirate King, Regicide, Serial blackmailer... whatever they are I like the idea of only showing a small number to the player rather than the full list so you can see them as a sort of quest metagame. If you only have 4 possible achievements open at a time you're much more likely to try to achieve any single one than you would otherwise... I will learn to be concise one day...
