You don't have to do something. If you want it - do it. For yourself, not for us. You are not paid for it, you are doing it for your own fun. Also, no one can give you any warranty that your submission would be accepted.
Right... Only problem is like I said I don't exactly know how to go through the process of writing and submitting it maybe you can help me with that Etis since you yourself have written for the game, or at least guide me to the right place that tells me how. This is after all my first time writing for TiTS but it isn't my first time writing for a game.
Also, I guess this would be up to Fen and company if my idea ever is to be implemented. I am still unsure as to who would sell it I've already thrown around a few ideas already but I am still unsure. I also have yet to come up with a name for it can someone help me brainstorm some ideas for names?
