Larger game teams are often a bit more experienced at working with writers, which is often a huge relief. However, it also means that there are more people wanting to wander around the narrative kitchen telling you how you should be making your story pies.
The best advice I have is keep writing, keep practicing, keep winning, losing and understanding the difference. Never stop learning, never stop pushing yourself. Then find yourself a team you can work well with and help make awesome things happen.
