Yeah, I thought of that one too, but what about the structures? Are they destroyed? Do they convert to your race specific structures? Or do they stay the same and you can then use a novalith as the advent?  

they sound nice, I especially like the restricting fleet size. it might be hard to check that though, so maybe you should go into a 'do not research tech xy' and include the fleet research there. less flexible, but maybe easier to realise. and it would go along with other techs like carriers or starbases or particular starbase upgrades.

also, I though about tech trees and had an idea. since these are so different it does not make sense to trade them directly. but you could sort of exchange knowledge on similar techs like starbase contruction, hulls or the like which would give both sides a bonus to research cost or time. or maybe a better idea is a tech treaty where both sides get some time or cost boost.

I'm pretty sure it's an RTS, Craig let slip in some interview that it'd be a strategy game like we've never seen before.

...? You bolded it, and there's the phrase 'strategy game' a few words past that too

Sorry meant to say RTS but with influence from the RPG gaming world.  And it was from the March 4 podcast on Gamers With Jobs.

Sins 2?  Sins of a Galactic Empire?   

I hope they stay Sci-Fi, for some reason, i've grown out of Fantasy 

I doubt they would either, way tooo many sinners out there.

Me too. The last strategy game I played that was fantasy was Heros of might and magic 3.
