I'd caution people to maintain perspective - how much game do you think you can get for $1.1M? This might be Obsidian's dream project but they will still (likely) be very constrained by budget.

I want loads of OPTIONAL companions…

And 5 classes?….

…I want a remarkably fledged out spell and counter spell system worthy of comparison to BGII….give us a magic system with incredible breadth!

… I'd expect new land masses, plots etc.

Plus Mac, Linux, housing then pay for boxes, cloth maps, take out shipping…

Don't expect a commitment to "loads of optional companions" until they have a lot more money on the board.
