Add a chatting interface like world chat private chat adding friends and fighting in friendly matches and challenges and also add a system of alliance guild better make it PMDA(park management and development association) which will have members who can help each other grow by sharing a limited amount of resources per day and there will PMDA tournaments where players will compete in groups and win rewards like DNA ,GoLd and food etc. But the chatting system is a urgent necessity because a online game without chatting interface is a little boring on the edge thank you
