Imperial Glory is one of the best RTS games i'd say, If you're a fan of games like Age of Empires or Divinity Dragon Commander or anything that's like that then this is your game.
For a game that's from 2005 it's still quite a blast, i'd play it for about 3-4 hours non stop and for a game like that, it's quite an achievement.
Alright i'll start by saying you need to play this game for ATLEAST more than 5 hours to COMPLETELY understand how much content it has, at first it does indeed look ugly and really half-♥♥♥♥♥ with it's fair share of bugs but it's really fun, though one of the really annoying things is you can only play as one of 5 europian powers, and there's about 15 or more civils so it feels like that's been completely ignored or just rushed at devoloupment.
Anyways you have two ways to play the game, A "Total Victory" type of campaign where you HAVE to unite the entire map, as in just fight every single dude who says no, or just buy every single country (except for capitals which you can't buy :<) till you get the entire world in your hands, or a "Score Victory" where you just have to get the most score. (just build build build and spam peace everywhere.) and the other way is to play one of the four battles that are all related to France and Napoleon at the early 1800's which is a bit of a shame really.
The "Total Victory" is pretty much the best way to play the game, it has the most content and would take you about 15-25 hours to complete atleast one campaign with that way.
Since it's the best way i'll start by explaining it, first off you pick your civil, then you have one of three ways to completely dominate a country/civil, One way is just buy everything they have till they only own their capital, Then just invade that. There's also a "Peaceful" way to completely annex them via just building newspaper offices and consolates and loads of other buildings to force them to like you all the way till they give you everything they have (units - land - resources) This way is gonna cost you ALOT but it's really worth it, and of course it's worth it later on since you get like 4000 gold each turn which is abit overpowered but still is fair since you really need gold at all times along with other resources. Third way is to go with a large army with/without help of anyone else and just try to completely destroy your enemy, I'd go with peaceful since the A.I generates a big army in somewhat of a short while.
Now i would NEVER recommend speedrunning this game as it's also kind of impossible, i'd say just try to get as many allies as you can and build a strong civil.
At first gameplay feels abit slow and also earning resources is abit slow but you quickly improve yourself same as the A.I.
Also the A.I devoloups quickly same as you and it fights somewhat good in battles it feels like you're not fighting an A.I, still you can get an edge over it so i'd say that's good enough.
So i said alot of things and overall the game is really good but let's start talking about the bugs and the annoying things that we all hate.
First off like i said above ^ the first things you notice is there's not that many battles and or ways to play the game which feels like the just rushed it and also you can't play as every single civil.
And when i said map/world map, the world isn't complete. It's mainly europe and north africa and west asia so it's really not that much, and there's not that much attention to detail, ottoman empire has just 3 territories and all of them are REALLY large, then next to it is just Egypt which feels like there could be way more attention to detail there.
Also when the A.I hates you, they literally hate you, they'll completely deny EVERY single political related crap you send except for improving relations with SO many resources or buying territory/land from them which also feels like they lacked detail there.
Anyways to just not make this longer, Overall the game is great for a 2005 one, If it's under $10 i'd say it's a must own but more than that then it's not worth it unless it gets updated and adds more polish and attention to detail. (mind you the high/ist resolution is 1024x768) so i'd give it a 7/10
