Strategy game you recomend;;

I saw later that your question is more along the line of the topic title rather than the description, so I'll throw in some more RTS titles:
Ground Control 1 (best RTS of all time in my book)
World in Conflict (spiritual successor of GC1)
Earth trilogy (2140, 2150, 2160).
Total Annihilation, preferably with the Escalation mod.

You should reinstall those Cossacks games and play them online with real people on gameranger or hamachi or whatever is the service called that lets you play old games in multiplayer with other people these days.

I would say Crusader Kings 2 also although it has a steep learning curve.

Try watching some Youtube videos by Arumba. You'll learn much faster just watching 1 or 2 episodes.

Χαχα, θυμάσαι και τι λέγανε; xD Γαμάτο φαίνεται και το Caesar III. Και εγώ καιγόμουν άσχημα στο Age of Mythology και Age of Empires. Τώρα πια παίζω Civilization V. Μήπως θυμάσαι ένα game, στην Ρώμη πιθανότατα ήσουν (όχι σίγουρα), που απλά επεκτεινόσουν και θυμάμαι σίγουρα ότι είχε διάφορες επιλογές για τους κατασκόπους των αντιπάλων σου: να βράσεις τον κατάσκοπο :P , να τον κλειδώσεις σε ένα κελί και να εξαφανιστεί για πάντα, να τον διώξεις από την πόλη σου, κλπ. Το είχα βρει σε demo από ένα περιοδικό πριν αρκετά χρόνια. Ξέρεις ποιο είναι; :P

Υπάρχει και το Grand Ages: Medieval, που φαίνεται αρκετά ωραίο, το Anno, που είναι σταθερή αξία, και το Tropico, που είναι φοβερό, αρκεί να σου αρέσει να είσαι δικτάτορας. xD Μιας και ρώτησα και τον άλλο, μήπως θυμάσαι ένα game, στην Ρώμη πιθανότατα ήσουν (όχι σίγουρα), που απλά επεκτεινόσουν και θυμάμαι σίγουρα ότι είχε διάφορες επιλογές για τους κατασκόπους των αντιπάλων σου: να βράσεις τον κατάσκοπο :P , να τον κλειδώσεις σε ένα κελί και να εξαφανιστεί για πάντα, να τον διώξεις από την πόλη σου, κλπ. Το είχα βρει σε demo από ένα περιοδικό πριν αρκετά χρόνια. Ξέρεις ποιο είναι; :P

i'll also recommend the other "endless" games- endless space and dungeon of the endless.

Funny thing is, I opened one RTS game on steam store and among "More like this" there was Dota 2 :F

huh. didn't know the remake was going to go Early Access. Think that makes it the 3rd time I'd actually be interested in supporting an Early Access project. Thanks for pointing that out :)

Realy? Including Red Alert 3, Red Alert 3 Uprising, the entire Tiberium universe, Dune, Dune 2 The Building of a Dynasty, Dune: The Battle for Arrakis, Dune 2000, Dune: Battle for Emperor? Then theres also Ground Control games, Krush Kill N Destroy Xtreme with expansion and Krush Kill N Destroy Crossfire? Then theres also State of War, a good old rts. The Warcraft games, Warcraft 2 Tides of Darkness and the Beyond the Dark Portal expansion., Warcraft 3 Reigns of Chaos and the Frozen Throne expansion? All blizzard games have great multiplayer possibilities even till this day if you get them running. Theres also OpenRA and CNCNet if you wanna play command and conquer games online, can download from the command and conquer communications centre which also has other great games i highly suggest such as Twisted Insurrection. Theres also the Commandos franchise, its great. Theres also various Starcraft 2 fan made expansions that you might not have played, made offical by blizzard themselves like Starcraft Insurrection being among them. Then theres also Act of War and Act of Aggresion, great strategy games set in modern days. (Sorry if their not in medieval times like Knights of Honor), theres also the Spellforce strategy game franchise, might be great to look into, seem like good games, most of them atleast. Theres that newly 1 man created great strategy game called Warshift, could be worth a look. Company of Heroes games are always there and their somewhat neat but hard. Supreme Commander games, Total Annihilation. Theres also the Earth games such as Earth 2140, Earth 2150, Earth 2160. Lastly if you run out of strategy games to play, i highly suggest for you to try the Anomaly games, they may be tower assault (mostly) and tower defense games but their exciting and demand alot of strategic thinking. Anyway, if you crave for strategy games, all of these ive mentioned ought to be great to try out if you can and havent yet.

in my opinion Wargame is one of the best strategies (for multiplayer, Al is too weak... but you wont figure it until you try multiplayer)
It is hard to take serious other RTSs (without recon, land-shaft differences, etc) after wargame and it's highly addictive since you begin to understanding it. Big learning curve tho... like Eu4 for example, another great strategy. Those are my two favorites.

Armello is pretty casual and random board game, nothing to talk about.... it's cute, would keep you busy for 10 hours or so until you realize its shallowness.

Yeap, I own it and its something different if you understand me =)
Search for gamesfoundry at twitch if you wanna check live streams from devs ( gameplay, progress etc. )

Well,the first one and Brood War.
The second one just didn't win me over.Particularly its campaign.

And yeah,S1 and Crusader were the best.Legends was average,S2 was meh,S3 was just plain sad.

SC2 is a money pit. Asking three times the full price for something that should have been one game only went beyond Activision levels of greediness.
