How real are project amenities in Delhi?

Builders always oversell amenities, it's a huge red flag for me now. I'm looking at places like DDA Freedom Fighters Enclave and honestly, I'm skeptical about what actually gets delivered. Do clubhouses and sports facilities really get used, or are they just for show? My main worry is if the promised green areas are actual open spaces or just tiny patches. And what about maintenance charges? Are they genuinely value for money for the service quality, or just a black hole? Any tips on what to look for during site visits to gauge this stuff? Hope this helps someone else too.
