I think they do look good if you're willing to spend the time and effort on them (even if it's frustrating). Game-wise... Well, there are lots of suitable sci-fi skirmish games out there that you can use instead if you prefer.
See now you're making me think about doing something with them again
Also like the look of the Pathfinders and jetbikes in the new Kickstarter, so I'll definitely look at them when they're out.
