What nobody tells you about new build quality.

The actual build quality after a year is what really matters, not the brochure pics. I'm looking at Gaurs Sports Wood for my first home in Noida. My parents keep saying new buildings have issues later. Does anyone there face cracks or seepage after living for a bit? Also, how's the children's play area? Is it actually safe and well-maintained, or just a token? I want it to feel like a real home, not just another concrete block. Honestly not sure what to look for.
