Not unlike other AGEOD games I've played in the past, the game mechanics for Pride of Nations look like they've got a lot of potential to be really good. However, also not unlike other AGEOD games, the user interface of the game is not up to the task of the mechanics. Lists of nations that you have to click to scroll down one at a time, clunky and variable scrolling speeds for a map (and you'll spend a lot of time scrolling across the map), a painfully limited messaging system (you have a new turn, here's 157 new messages....! There's no filter, no way of focussing things). It's playable, but it's the kind of game that you would literally need to have a notepad and paper next to you to play properly, because the game doesn't convey enough of the required information itself (or have a built-in system of reminders/overlays that is effective). The diplomatic UI is particularly obtuse, for a game where (unlike many other AGEOD games) diplomacy is very important.
The in-game tutorials are also very limited, and nowhere near up to scratch for a game of this type. They repeatedly refer players back to the manual, but for a game that as far as I know was only released digitally, relying on a manual is a bit silly. At the very least, make the manual text available in-game, and far more preferably available contextually in-game.
If you can look past the UI to the game mechanics, it really does like like there's a potential gem here. I haven't played enough of it to be able to rate the AI, but AGEOD games tend to be fairly strong on this front. The mechanics look great, the attention to detail in set-up situations and a decent number (4-5) of extra scenarios as well as the grand campaign mean there's a substantial amount of game here, but the tools given to play the game are not up to scratch, and you'll have to persevere through them to get to the gameplay underneath.
