Have you seen SH5? Have you seen any worthy content in SH5? Do you consider SH5 a finished product would YOU put it out for sale the way it is right now? I know you are well intentioned and all, but if you answered yes to the last 2 questions then God help you because no one on this forum will
If you answered no then you have your answer right there. I personally LOVE your idea and I would support it 100%

Ubi however will not give a crap. They care about money your idea would not appeal to the masses but a select few. Select few do NOT = large profits.
Perfect example SH5 no content just eye candy. Amazing eye candy no question about it but nothing more
You should be talking to the community devs like the people that made GWX and NYGM to name a few.
