Original War is a hidden gem.

Ashes of the Singularity is great, I'd recommend you to make use of that win

Following this thread, I love Company of Heroes, any similar RTS or other World War 2 or other major war RTS?

Age of Empires online, the official servers shut down but you can still play with a fan mod called Project Celeste.

Warwind since it hasn't been mentioned yet

love me some a-symmetrical RTS

and apparently warwind II is on gog now too, when did that happen...

Rush for Berlin is great if you like WW2 RTS

Herzog Zwei

Despite the title of this article, I played it all the time against my brother when I was a teenager. :)

Crusader Kings II
Cossacks trilogy
Company of Heroes 1 & 2
Tropico 4 & 5
Cities: Skylines
Civilization 4 & 5
Total War series
Age of Empires trilogy
Command & Conquer: Red Alert 3

If you want a new/recent RTS, take a look at Spellforce 3. It's really hard to find new games in this genre, since they don't sell very well and making them is a bit more expensive than adventure/action games because players expect a long campaing, good AI and decent graphics.
AoE 1 HD is releasing today on Steam/Xbox game pass.

Other than those 2, I can't remember a single good RTS released in the last 2-3 years.

Settlers 3-4, Original War, Total Annihilation, Zeus/Caesar III/Pharaoh/Emperor, Banished, Hearts of Iron II

well Age of empires definitive edition have just launched on steam , one can never have enough of AOE xD

Starcraft 2! Don't need anything else. :)

Caesar III

https://youtu.be/ZtQy74Vquyo?list=LL2m3oRPz3sGu5T4qPfrNyIA - standalone mod for WBCIII have lots of changes (mostly good but some I personally dislikes);

Original - Warlords Battlecry III - epic game with lots of nations. You play with a hero who saved between games, get exp for new skills, spells, items;

Seven Kingdoms II - a bit hard to get in, you can play humans or monsters, it have HD version;
Rising Kingdoms - simple game with a heroes;
Kohan II - King of War - you command armies instead of singe units, every army 5-9 units which you can manage. Morale, exp and heroes;
Paraworld - simple game with a dinosaurs.

Also I would recommend Impossible Creatures (which was mentioned above).

for me total annihilation is one of the best rts ever. maybe even THE best.
i tried supreme commander one or two times but it didn't really grab m (yet).

also that age of empires 1 remaster was just released a few weeks ago.
