TL;DR: This game shines for it's editor and Multiplayer. Don't get hyped over the campaign.
Forget the Singleplayer skirmish/campaigns(unless you want to get campaign mods/missions). The Editor is where it shines. You don't even need to know how to script to use the editor(I ended up learning alot of scripting and stuff because I like flushed out missions). Being able to create a huge offensive is insanely fun. And, it is VERY easy to make the maps you develop/edit available in Multiplayer. If you come here for the Singleplayer campaign, you might be dissapointed. The missions are repetitive(they're all the same). Each mission is a map with about 3 rows of 3 objectives. Each nation also has one "stealth" mission, you still have to take the objective, and one defense mission. It is fun at first, but it gets to the point where it is too repetitive.
