Personally no. Sega can't have its cake and eat it too. If they refuse to lay down money, then they should hand over the IP to platinum and risk losing the IP to platinum in the event of a successful crowdfunding campaign instead.
The problem is they wont. They'll sit on that IP until Judgement Day and not do a thing with it. If they don't have the risk of losing money however, they might use their resources to actually make the game.
That's not the point. Its like asking you to pay Donald Trumps bills when he has more than enough money to pay it off himself..tenfold. Its nothing to do with whether or not i want this game or not. Its the principle of it.
If I paid 1% of Donald Trumps electricity bill, and then he let me use his home theatre system for the weekend and take a beer from his fridge, that's more of a fair comparison. I'm purchasing something from him.
I can put down money to purchase a copy of Shenmue III, and that money goes directly to funding said game so when it's released I get my copy.
I can understand your stance on this, but I do feel that this is an interesting opportunity to take risks that would usually be written off entirely and never attempted. I don't really see why it's a negative, nor why Sega 'should' be funding a risky project themselves. Left to their own devices it's plain to see that Sega would rather spend money on Mobile Games instead.
