I originally bought this set for the minifigs, but once I had it, I realized that it makes a great play set as well. There are, however, certain issues with the set. We'll start with the minifigures.
Reaper: This guy was the one I was most excited about when I originally bought the set. The printing on his torso and face is awesome and his trench coat cape piece is too. His shotguns are also a lot less bulky in real life then how they look in pictures. The only issue I have with Reaper is that he has no leg printing. This is disappointing because if they had continued the print down from his torso and onto his legs, he would have been my favorite character. As it is I'm giving it an A-.
Soldier 76: This one's okay, but just okay. Like Reaper, he has no leg printing which was disappointing, but I also have some issues with the printing on the torso. There's a sporty little '76' on the back of his jacket, and while I'm sure it's game-accurate, it just doesn't really fit with the over-all character. I would have preferred LEGO to go for a more cyborg warrior type. I also feel like they should have made at least one of the characters have a double sided face. Ideally it would have been Reaper, but at the very least they should have made Soldier: 76 another face. His gun's clunky, but still cool. B.
McGee: Probably one of my favorite characters from the set, he has both leg printing and some very cool torso printing. He comes with both a hair piece and a hat, so you can swap it out. He also has a cloth handkerchief thingy around his neck which really completes the picture of a cybernetic cattle wrangler. I have no real issues with this character but I don't think he's the best he could be. A.
Truck: The hover truck makes up the main portion of the set. It's good, but LEGO leaves much to be desired. The front half of the truck is perfect. Looks like a very hold trench pickup. The back half really needs to be beefed upland it would have been nice if they had continued the color scheme all the way through. The windscreen and roof lift off to reveal a cab with a seat and steering wheel. On the under half, there are some wheels from trains so that you can roll it around and make it look like it's hovering. Well, they don't roll very well, and if you look at it from a few certain angles, it looks very weird. Other then that, this is a good build. B-.
Building: The buildings okay, but it's almost the deal breaker for me. It's very top heavy which makes it hard to play with. There's also no interior decorating except for one candle. The roof leaves much to be desired. However, the frames around the windows and doors are very cool, and there are some very detailed stickers on the walls. B-.
Power source thingy: Not really sure what this is since I haven't played the game, but it's cool. There are some rare 1x1 brackets used in it, and the translucent radar dishes are awesome. A.
Fruit stand: Not much to say here. It's a fruit stand. No real issues but definitely not the highlight of the set. Th lights are made out of yellow jewels and the way they built the red pig-like thingy on the rope is smart. A-.
Final thoughts: While this is a good set, it leaves a lot out. The minifies are definitely the best part to this. It's also surprisingly fun to play with. Other then a few cosmetic and structural issues, this is a definite need to any Overwatch® fan's wish list.
