That sounds possible. It depends on what I am writing. I can do 100k of a simple story in two weeks. If it is a compicated story with a lot of characters and themes 100k could take all seven months. I assume this game is not exactly going to be Shakespeare. (It can be if you want). Those numbers don't scare me. That having been said.
I don't count words and I don't worry about deadlines. I will do my best and if that is not good enough que sera sera. I know this may not be what you want you hear from a parnter, but I think it is a better attitude to have than stressing, or rushing out trash just to make a deadline. The way I see it the game will take as long as it takes and it will be as many words as it needs to be.
If I am not right for the project then I am not right for the project. I am willing to give it my best shot. I am not promising you more than I can give. I am trying to be honest for both of our sakes. I don't want to waste your time.
Do you want to work with me?
