A game with a lot of great ideas and a fair number of bad ones.
But first, let's talk about what it does right. Infantry tactics, with individual unit advancement is very welcome. A continuous income system is also very nice (always dislike the limited ones), and whole feel of the battle field are quite nice. Graphically it is also quite good and for most purposes the interface is quite good. That you get 1 campaign in the original, and 3 extra for each expansion is also very nice.
Where it starts falling off the rails is with difficulty. I'm not by any means an RTS ace, but I've been able to get by in the single player of most every RTS I've tried. CoH, not so much. Difficulty is all over the place. Some missions are boringly easy, while others are shear insanity, and this on the so called 'easy' difficulty. This seems to be one of those games where the developers just don't get what easy means. Like many another game, they seem to think easy means 'slightly less insanely hard'. What is even more odd is difficulty is highly variable even within the same mission. One time you'll play it and the AI will be totally crazy offensive, the next you'll play it and it is like the AI shut off. And, if you have any notion of cheating your way through, drop that notion right now. There is no cheat codes of any worth to aid you, and having hunted around, the only 'trainer' that is freely available is should be better termed 'AI uberizer' as all the training options affect you and the AI, which generally can make much better use of such.
But, it's not just the difficulty. There is several other little things that are contributing to me losing my initially good impression of the game. First is the unit cap. It is just simply too low. You shouldn't be running into the unit cap constantly, and I am. There is not a single mission where very early in I wasn't capped out. And, thing is, you're not very strong at that unit cap. You don't feel like you have a huge army, instead you feel like at best you have an adequate army. Add to this, there is lots of bad choices around this. For instance, you can have your soldiers man various pieces of field equipment, great mechanic by itself, but when you find yourself running low on cap, you often start to curse that you spent troops on equipment and now can't have them abandon it. There is no easy way to dismiss a unit so you're forced to get them killed if you want to swap out. Also, the cap is odd in that each soldier counts individually towards it, but your units are composed of separate soldiers. This can easily lead you to inadvertently eating up your cap on a fresh unit, and being no longer able to reinforce an existing unit back to full strength.
Another issue is the cutscenes. They have a terribly habit of being annoying. You are in the middle of a fire fight, trying desperately to manage your troops, and a cutscene interrupts you. It doesn't get you killed, generally, but it is aggravating to have your train of thought interrupted in this manner.
Lastly is just some minor interface gripes. Esc, normally bring up the menu in most games, not here. For some reason you have to press the on screen menu button. You can't tell a unit in a building to reinforce, forcing you to move it outside just to have it reinforce, just to put him back inside again. And lastly, the minimap is not terribly useful for finding units in many battles, particularly if they are hanging around one of your own buildings where they can easily blend in.
All in all, this could have been so much better a game with better difficulty control and a less intrusive unit cap. As is, I can only recommend it to those RTS vents who are looking for a tough experience in the single player. I can't comment any on the multiplayer as I'm just not into that scene, although judging from what I've seen it looks like it would at least have promise. In the end, it was worth getting in the Humble Bundle, but don't think I'd pay for it new.
