Good, actually. While i do beelive that without utopia some Ethics are underperforming (i.e. whats the point in materialism if you cant pick mechanist and so, robot maintenance bonus will not work for long period of time; or the F. xenophobe which is worse then F.Militarist+basic xenophobe unless you pick the purifiers which you cant since you have no Utopia) the imporovements to game mechanics is nice overall.
Missiles still suck, but not that much, i'd say they on par with lasers, though kinetics is still better.
And the fact that planet blockade not giving any warcsore is quite a change - now you really have a reason to look at army-related bonuses.
