That looks more like Empire Earth 4.
This is why I liked WC3 so much. As much as I loved Starcraft 1, battles, especially in BGH, were just massive raids and it was difficult to micro all the units. WC3 understood this and made each unit stronger but more expensive, so micro management was the key to winning battles, not just massive zergs. The RTS genre is not doing great, in my opinion, because it still takes an incredible amount of dexterity and mental skill to be able to do that kind of micro management as opposed to something like FPS games or MMOs which are more about playing smart than aiming correctly or having the best gear. RTS games are much harder to master in that regard, and therefore less appealing to gamers. I love watching pros play them though.
WC3 literally killed itself by being too micro heavy. Ever wonder why everyone and their mother played DotA Allstars instead of MP? The custom game type that nukes everything except microing 1 hero unit? It's almost like it was manageable compared to base game to normies. That's just Moba, then you look at other popular custom games, and all of them just get rid of most of the game and focus on either managing 1 unit, usually hero units, or 1 builder building shit, like the 74000 tower defense maps.
Microing 1 hero. That's the peak of what people are willing to put up with. Microing multiple 12 stacks and switching between heroes and casters on top of building, researching, resource gathering? They'll just leave for the first alternative that gets rid of a bunch of shit while keeping what they like. And so they did, to Dota/LoL. Now, you can't put the genie back in the bottle, as SC2 has shown. People will no longer put up with that level of micro, period. They'd rather go autistic on their preferred hero in League, which is sth even a child can do.
Honestly, the genre as a whole was a victim of SC's popularity. It made everyone, players and developers alike believe a high skill ceiling was the core of RTS. Which wasn't the case, that was just SC. C&C up to and including RA2 was so fucking easy as a game to play, that a 6 year old could enjoy it while using only a mouse. But then in the 2000s devs wanted to be the next SC and the most vocal people on the internet were the MP/SC types, so they fed into eachother. The SC audience that got bored of BW hopped game from game before ending up playing DotA to pass the time until SC2(which most of them then gave up on and went back to BW or LoL), and the audience of all those old series withered away due to the shift in game design, like C&C.
