krish Thanks for your interesing, we love open world games that require object management as culling to save performance like AAA games do.
Let's wait to get more people to join this group and I will invite you (Use Trello for better organization and reference.) You should consider register Trello https://trello.com/ , it's not useless and annoying, we use it for video game planning and production, it was useful. Sometimes chat doesn't help due lack of organization. Maybe we can wait until 2 weeks, I will PM you.
