Very different. Sedition wars was run by Studio McVey, owned by Mike McVey who has had loads of previous experience in the gaming industry. He also had a successful company with backing to achieve the boardgame. Mike has worked for GW, Privateer Press and Crocodile Games, 3 massively successful companies where it is easy to pick up contacts through networking. I congratulate Mike on his success, and I have a huge amount of respect for the guy.
Warzone Resurrection is run by a smaller company, creating a larger product. They are having to pay for licensing (which is a large part that sedition wars does not have to), concepts, sculpts, resculpts, more resculpts, even more resculpts, printing, 3d printing, more 3d printing, sometimes more 3d printing, rendering, master molding, production molding, packaging, graphic design, marketing etc etc etc...
It's a huge project, with huge funding required. Currently everything is being funded by Prodos Games with the intention of breaking even and eventually making a profit.
Prodos has been sending out early products to people they feel will use the miniatures for marketing purposes (popular bloggers and youtubers) and also to people who have assisted in the success of the KS and Prodos Games on a whole.
Hopefully WZR will end really high, and they will be able to grow the company further to achieve goals faster in the future. However, when you consider it is currently 4 people and some freelancers, they are doing really, really well.
