Pros
Pro No complicated trees, no research
Just classic RTS action without days long learning curve. All the intense fun, none of the tedium.
Pro Great single player campaign
Also great for quick instant action skirmishes.
Pro Supports up to 8 players
Has 6 distinct playable races, co-op teams and custom map support.
Pro Extensive construction kit
Not only lets you make your own map, it comes with all the tools needed to make your own RTS game using the engine. (Though most are hidden in the games folder, the construction kit is one of the first things you'll see once you start the game).
Cons
Con Predictable AI
The original 1.0 release on bare retro hardware was actually quite intelligent. Over the years something has gone wrong. Still one of my all-time favorites though.
Con Joining a multiplayer match is difficult to do
Multiplayer has never been updated. Though it still works, it requires professional networking experience.
Con While multiplayer is a plus...
At no time was this easy.
