Otherwise, maybe a simpler answer would be - something to match the current SH games? You'd probably need at least an equivalent of 12-15 people working full time for about 2 years. How much do you figure that would cost? You're probably looking at at least $1 million there. Now add in things these people will need to work - computers, software, office space. Now add licensing fees for technology. Now add a marketing budget. Now add publishing costs.

So the short answer is probably $2-3 million even with modest effort.

But like I said, unless there is a business model, the money is actually irrelevant. Development and funds should fall into place themselves as long as the whole project has a viable market and ways to reach that market. Simply paying someone to create a 'dream game' is inviting a business disaster (and possibly a poor actual game, too).
