Brochure amenities are just a marketing trick, right?

₹1.2 Cr for a 3BHK in Shiv Krishna Valley feels high. My wife's worried about the construction quality we saw during our last visit, like small cracks already. The brochure promised a big clubhouse, but what's delivered vs. what's usable for kids? Are maintenance charges worth it for actual service? Just want a safe, genuine home, not just fancy pictures.
