Agreed, these figures look neat, but overall, they seem like they're from a video game or anime I've never seen. The hammers and axes look like something from Destiny or Final Fantasy franchises. Most of us on the site are interested in military figures in the WWII - near future timeframe, so the sci-fi route isn't going to get much traction from our small but loyal following here.
If they were $10, I'd probably spring for a few just because. But I have to REALLY love a 4" figure to pay $30 boutique prices, and even then I grumble about it.
That being said, I'm glad these exist for the people who are jonesing for 4" sci-fi stuff.
