Really? I enjoyed the RTS parts just as much as the rest. I was expecting Sacrifice reborn + Metal, and that's what it was. It's about time someone made a new game in that subgenre, I can't think of one since Sacrifice, and that was released almost 10 years ago.
I wish it had been a bit longer, but that was exacerbated by my rushing through the story missions to see what happened next. I'm currently playing through the game again and taking my time, and I'm still finding new little touches.
