I have found that the in-game tutorials are very unhelpful. The Diplomacy one was bad enough, but with the 'release a general' tutorial, it kept telling me to click on a highlighted menu; I had opened the locked generals panel (by guesswork) but I could find no highlighted menu whatsoever. I gave up...

You're right, of course. I was just so disappointed to be greeted by that within a minute of starting my first game. It's not what I expect from AGEOD.

And,at the start of the historical campaign, the first unit available for recruitment is "FAC_ADJECTIVEM_FBA Colonial Brigade (Afr.)"

London is south of the Thames, the entire regions known in Britain as "The West Country" or just South West England is named "Cornwall" (as is the county of Cornwall, also on the map), and so on. Do AGEOD ever check these things?

Do AGEOD read this forum? The title would imply I had found something wrong in the game, and all I get is total silence.

Not differentiating between Dreadnoughts and Pre-Dreadnoughts is a major simplification that can only damage the game. Not impressed!

I suspect - and hope - that this was not the intended unit name.
