A few ideas that would make the game much better (and a few bug reports):
0. Sentry mode: I would LOVE to have a setting where ships in sentry mode only came out of sentry mode when an enemy unit came in range, not friendly units (allies, civs not at war). This gets annoying. It would also be good to have a "sleep" mode that will not wake at all. I build "sensor ships" with a huge sensor range, and they pretty much wake on sentry every turn. I would use sleep mode for those.
1. I am constantly fighting the approval/tax problem. In fact it often pisses me off to the point where I don't want to play anymore. This is when I have say 10 planets, 9 of them are at 100% approval, and another is at say 40%. Nothing I do gets that 40% up, short of lowering taxes, which kills my income from happy planets needlessly. So, IDEA: what would be great is if you had a govenor that adjusts taxes on each planet based on a set approval rate to maintain instead of a flat global tax rate. This would make "us" HAPPY.
2. Add a window where I can delete old designs (design files) regardless if I have researched them or not. Mainly I would like to see the bug where multiple ships of the same name show up as you upgrade.
3. Add the income per turn next to the total cash on the bottom left. I am getting sick of going to the tax screen just to check my bottom line every turn.
4. For population info displays (number), add a "population" out of "total possible" so I know how high it can go.
5. Farms say they provide food for "8 million people". What? I don't see how that translates to billions increase. Is this 8 billion? That means a planet would go from 5.00b to 5.01b if it rounded up on all fractions, otherwise you would need to build 5 farms just to get to 5.01b. Obviosly this is not what was intended.
6. This would be a big feature, but I wish there were more "hyperlinks" on technology listings. For example, in the tech discovered screen, it would be nice to hold my mouse over a future tech listing and see what that future tech does. Same goes for the diplomacy screen. Obviously this would be less important after I have played for 1000 hours, but that will take a while
7. There is some funkiness with fleets when you disband and reorganize. Sometimes I make a new fleet, move it, and some ships that are not in the new fleet, but were in the old fleet start following.
8. In general, I have been rather displeased with the campaign games. The first was an ok intro, and the second ok too. The third I couldn't win, so I did the alternate, which was the "win over this race as allies" mission, which was still ok. The next two sucked because I was so far away from the Dreads that I had to spend tons of time building up with range, speed, and attack/defense to get to them before the other races won it for me (which they did). In general, they just were not as fun as they should be I guess. Not sure what you could do about that. I am sure that playing a normal game will rock.
