What Strategy/Manegement Game Has A Great Visual UI Design And Why?

Not really into strategy/management games, so... have a bump c:

Command & conquer series (tiberian sun, red alert, tiberium wars etc.) obviously , i find its sidebar very useful and simple, it actually makes you focus into the game, not into the ui . The UI is just great for those who love fast-paced strategy games
edit: i just realized you meant management games , sorry but at least you got an opinion :D

Sadly I can't really help, haven't played many of those games in the close past.
I remember that rollercoaster tycoon had horrible UI ( menu of the menu of menu, no explanations, hard to find additional popups) and that Cossacks / age of mythology had pretty cool, but IMO standard(ly good) UI and control scene, even if we ignore quickbuttons. But having a grid for buildings / commands isn't a great or unique thing, right? :)

Football managers series has a great layout, and even support 3rd party skins.

Have to mention Starcraft just because of how smooth it has to be to be useful in competitive gameplay, every keyboard shortcut being well thought out, and for being uniquely themed for each of the three main races.

That said, I really like being able to select literally hundreds of units at once in Total Annihilation instead, and that also had some pretty good keyboard shortcuts for specific selections and groups.

SimCity 2000 felt pretty nice, too. Usually easy to bring up the graphs you wanted with few clicks while not needing to cover the screen with them.

Homeworld did an admirable job of strategic navigation in 3D space.

Let me bump this and take the chance to say thanks for all the examples, I have checked a few of the UI designs but haven't really found what I was looking for. Maybe someone else still has an idea of an exeptional clever/great UI design?

Homeworld Cataclysm, minimalistic UI with nice sift between game and map and in map mode you still have full control over units.

I think Master of Orion 2 has a pretty intuitive UI. It's not the prettiest one out there, but it is surprisingly easy to learn. Its UI would scale up pretty poorly for more complex games though (as far as 4X games go, MOO2 is relatively simple. Simple, but fun). The recent Master of Orion actually feels a bit less intuitive in its interface design, although it is better looking (that game is also quite enjoyable, by the way)

my 2 cents.

UI in strategy & management games are badly designed in term of UX.

honestly how many games you know where the players community goes into creating database and tools site/app to help players life ?
sounds like something must be really missing for some fans to go to all that trouble.

any good software nowdays offer a silk and totally customisable interface. Any software that deal with data permit to build your own request/filter/dashboard (and save them for reuse).
I would appreciate those functionalities to come into games as a standard.
