"The set itself is fantastic, well thought out with lots of cool features. One mod i'd recommend is the extra airlock door in the shuttle docking hub, there are plenty of tutorials online for it, and it makes it a better model as it's just that little more realistic. But where i think lego shoots itself in the foot (again) is that there were no expansion kits for it. You have the main station, but they could have had an expansion kit with larger living quarters and a gym, and another one with shuttle repairs that could have been bought seperately and increased the playability of the set. As it is, i bought three of these and did a bit of adapting myself, but it would have been better with a purpose built expansion pack. I'd still give it high marks because the set is great, it just missed out because of it's potential to be better."
