Thanks for the suggestion Ambro. Scaling a UI is a tricky one because the graphics are raster (pixel based). Some games will stretch these pixels but the resulting quality is poor due to the interpolation.

I agree, I play at 1024x768 just so I can see the UI; any higher res and the eyestrain is just not doable over the several hours it can take to finish a game   

Thanks for the replies. I guess stretching the UI would be a bad idea as it would end up pixelated like you said. I like PeterPikers idea of being able to choose between a few different options though, perhaps just the normal size and then the option to make it large would be enough as I expect it would take a bit of time to resize the icons without them looking pixelated. Also with the price of HD monitors coming down now I expect more people will be playing in HD or above and so I imagine this would be a great help to many players.

Well obviously if your lucky enough to have 28" monitor the I don't think anything is going to look small. Bear in mind that most HD monitors are 24" though and so have a very high DPI which looks great although it does have a tendency to make user interfaces much smaller than they were intended.

Sometimes when I'm playing, I get caught up looking at the UI and get slaughtered....   Is there something wrong with me?

I know this won't be possible, but making the UI customizable would be cool too.  There's some stuff I never touch that I'd like to not see on screen.  Or to move the empire tree around and stuff like that...  Ya' know, that's just me being demanding.... haha
