I have a couple questions about backing now before it ends on 8/22: 1) If I back it now, will I receive the extra items from the $25 tier on the KS? (achievement, in-game item, and access to the documentary) 2) Has there been any word or hints as to the price? It costs $35 to back it now. If it's going to be released at $40, then I would just assume wait and pay $5 more at the end of the year. If it's going to be released at $50 then that would be worth purchasing now.
