Edit: I misunderstood the sets the above post was referring to.

Definitely need some stickers, at least, for this.

I’m about 80% sure you are being sarcastic at this point. Just to be sure:

1. The BlueBrixx sets print unique design elements like names, numbers, coloured lines directly onto the bricks. LEGO is known for adding packs of cheap stickers for most of that.
2. The ready room picture is, afaik, one of the more iconic objects associated with Picard.
3. The painting is 1m x 0.5m with some depth.
4. The Lego Millennium Falcon has ~2.5 as many pieces for ~4.5 as high a price. (Using the regular price, which is €189.95, btw, ten less than you wrote.)
5. Intricate details I cannot judge from the pictures. I suppose that comparing a painting set to a ship that’s several times as expensive may also not be the easiest to compare, even in person.

The Star Trek ships should be bigger and cost more, or cheaper and cost less. Not the same amount for far, far less.

That’s, like, your opinion. Personally, I think €850 for a single set is a bit much. I’d rather have 5 smaller sets for that price. That said, Bluebrixx does plenty of ships that are "cheaper and cost less", down to tiny sets for ~€10 each.
