First Loss is still en-bugged for me in 999L.
15 planets, 8 start planets, AI10s, lost one of my command centers and message came up saying I lost, but didn't get the achievement. Hrm... for that matter I didn't get any of the other achievements that I thought I would from reading the list.
Also assuming the numeric sorting level is "difficulty", 600k of crystal/metal achievement is easy not hard.
Maybe a class "2"/bronze if necessary, but really it's a 1 for most people I would think.
The "Control 110" is somewhere north of insane difficulty if it doesn't include your home planets if you're doing it in a multiplayer game. Even single player against an AI7 AI I'd think it's essentially impossible. Maybe "Control 100" instead? Or at least give it a difficulty of "6" (give it a dark grey colour to demonstrate the sheer exhaustion should you get there?
).
"Win X Planets" is unnecessary concise and confusing at a glance. "Win on X Planet Map" or "Win in X Planet Galaxy" is clearer and doesn't make me confused that it's the Control X ones.
"Nearing the End?" lacks a colon after the question mark like all the others have.
All those "difficulty X or up" should be "AI Difficulty X or up" or something similar, since that's what you call it in the configuration screen. Also shouldn't it be "or harder" rather then "or up"? Makes it easier on the translators.
Also the ones that specify "difficulty 7/9/10 or up" probably should have a limit to the minimum number of planets they can be played on. I'd suggest minimum 40 planet map, but this could make it somewhat more confusion then the rest of the achievements.
Mouse wheel doesn't work on the Achievements list to scroll up/down too. Also scrolling up/down with the keys doesn't move the scroll bar, even if it moves the list.
Can't easily tell the difference between a greyed out "silver" or "gold" achievement cup. Maybe give the background of that cell a faint shading of the appropriate colour? Or a popup tip that tells you when you mouse over the cup?
