That was great, I gave full 5 stars. I would have preferred to give 4.5 if I could but you can't. My only complaint is that although it was a lot of fun, I wouldn't want to play it again and it didn't last that long. For a single play through though, it's about the best I've ever seen.
I miss the challenge modes too and also the fun modes like the 10k one and stuff. But I think you are supposed to just recreate them yourself using the sandbox mode. I need to register to their site to do that though.
I like the way this game plays but I find it a bit short and a bit thin. There are only 4 maps and I just find it all quite a shallow experience. I find the game itself technically more fun than Protector 3 because there are more placeables and it requires more timing. But I find Protector 3 far more involving because it's presented like a long term game where you build up your wealth and team and stuff, which makes it FAR more fun to me. I wish this game could be more like that.
