Any good strategy games?

cmon guys, really?

I personally enjoyed Red Alert 3 a lot, especially in co-op. Unless you're looking for a serious game, that is :p

Total War. Any one you want.

Warhammer 40k DOW or Company of Heroes or Supreme Commander/2

Eufloria!

guys, under £10.. :p

Agge of Empires 3

Under $10: Toy Soldiers, very fun game. Over $10: Total War Shogun 2, my favorite strategy game, most fun I've ever had with a strategy game.

Crusader Kings 2. When it gets on sale, you have a perfect fit.

If you watched Game of Thrones/read A Song of Ice and Fire, and love backstabbing strategy with the individual characters in the main spotlight, this is the game for you.

Alternatively, get it on Amazon for $12.49, in the Paradox Bundle, alongside with 4-5 other games, some of which are quite noteworthy.

Company of Heroes

Well if you want something similar to Civ 5, then Warlock - Master of the Arcane.

It is 20 Euros from where I live, not sure about the price for you.

Age of Empires :D I played first more than 10 years age and it's still my best strategy game ever.

X-COM Complete pack is 11 pounds sadly :P Great games though, I strongly recommend getting at least X-COM: UFO Defense

thanks for the ideas, but all the good ones are over £10! ive looked at all of them under 10, not my cup of tea.....

Warcraft 3 is the best strategy game I have ever played, by a long long stretch. You won't find it on steam but you can pick it up for like £1 on ebay. both Dawn of War games are great, they're quite different to eachother so have a look at them both before you pick one up. Red alert 3, as someone already said too, is also great. Very like warcraft 3 (as is DoW1 actually :P warcraft 3 is just the best strategy game. Get it if you dont have it. Warcraft 3)

Age of Empires 3 Complete Collection, it is expensive but add me to talk if you want it.

Command&Conquer series, Disciples II and Heroes (but really very cool and awesome Heroes is only III. And it's not in Steam). StarCraft I and it's too not in Steam. Also Football Manager not bad, but it's 'another' strategy. And Comapny of Heroes.

£10 was enough for Civ.V GOTY on SummerSale (that's where i got him). You were late only a few days :X
If you can't join a little more to Empire Total War buy Rome Total War - Gold. Old but good.

I would say Men of War but its $15

Frozen Synapse. The multiplayer is great for short strategy action. Plan your moves and take your time. Then while waiting for your opponent move you can do something else.

Europa Universalis 3. It's set in the period from 1400 to 1820 and you can play any country you like: Resurrect the Byzantine Empire, colonise the New World as Norway or turn Ryukyu into an Asian powerhouse. It plays quite different every time.
The Complete version which includes the first two expansions costs 10 pounds at the moment but if you buy it, you should later buy its last two expansions (Heir to the Throne and Divine Wind) as well as they add a lot to the game. Oh and you can find lots of excellent mods for the game in the official forums.

Making History: The Calm & The Storm
You Control Any Nation In A War, It is A Great Strategy Game!

Warcraft III is my personal favorite strategy game, but if you wan't something newer you could get Shogun 2 or Dawn of War

Atom zombie smasher ! try it seriously =]

Supreme Commander 2. Greatest RTS I've played in a long time.
