These are just things that I enjoy in the game that I'd like to see more of.
a) Enhanced tech tree. Playing tons of space games over the years I've come to love having tons of choices for tech research. Dev's, look at SE IV and Sword of the Stars or the MOO lines for ideas. Having mulitiple ways to go enhances replayability immensely.

Better UI for fleet control. As I'm growing more comfortable with larger and larger games I see a growing need for a Planet list and a fleet list on the UI screen. Scrolling up and down with both on the same list makes it a chore getting what you want where.
c) Settled planet variety. Right now we face AI empires, how about a random inhabited planet or two that's not aligned? Through's negotiations and culture influence into a big new light if we could get allies.

Or a berzerker planet? Or a ....

d) Effectiveness of the battleships needs to be increased. Make them truly fearful, right now a mob of 10-20 cobalts can take a battleship out. If they are the Queens of the fleet right now they can't go anywhere without their attending court of smaller vessels so they don't get mobbed.
e) Involve the player in the DESIGN of large warships. Part of the allure of Dread Lords is the player designing their own warships. You include this aspect in sins and you'll have the wargame of this century. It'll turn into the new Elite.
f) Do things to enhance movement within player empires. Warp Gates, Teleporters, Warp Speederupers or something like that so we can shuffle our forces around to meet threats. Hey,if the pirates somehow can come into our back worlds from nowhere, they must have something like that.
g) Players of empire games love micromangement, but there's a point where it's too much. Namely, in combat. When a grouped mass of our warships enters a system the ships shouldn't peel off to find their own targets! Especially with a command and control cruiser present! Let us have Group commands that include focusing fire on individual targets, commands for defence/offence (homeworld 1)formations, commands that will focus on target order (No, don't run into those 9 gauss cannons!

) something along the line of frigates/crusiers/fighter/bomber groups, etc.
H) Make the contest for the planets more than nuke them into oblivian. Include a side game of planetary invasion (a la Moo II) where we can conquer cites and population, glean tech breakthroughs through sifting the rubble, etc.
I) Angry Critters with an Attitude in Space... How's about a space monster or two? They were cool in Star Fleet Command and Moo... Would make those pirates really look wimpy

Finally.. the games on my hard drive. I still have MOO 1, love to make a small snub fighter zerg... I still play SE IV, just to see if I can try another tech approach... I still play Sword of the Stars, love the tech tree ship design elements. And ... here's the oldest... I still play Star Legions, by Mindscape. A little dos game that has planetary invasion down pat.
Just my 2 cp. Thanks for an excellent game so far..!
