For people who haven't been following this thread (or have been following it but still "aren't following"), it may be good to distinguish playable modes from mode bonuses.
For example, CE Adv mode sounds like if you have it but I only have Adv mode, you'll be able to access areas, use ships, and otherwise do things that have a game-mechanics effect that I can't do, when afaict it's bonus swag and costume coupons. I'm still not sure what CE Skirmish means for someone who has what is currently available on Steam as "Guns of Icarus Online."
If the spreadsheet were updated so that all the checkboxes under "CE Adventure Mode" were also given checkboxes under regular Adv mode, and CE Adv were renamed to something like "Adventure Mode CE Items", it might be more clear.
On another note, it sounds like any backer, $5 or more would get to beta test adventure mode, but would lose adventure mode once it goes out of beta? Or would it just mean that they would be able to beta any changes that will come to all skirmish play?
Also, will the 4x packages confer closed beta access to the other 3 licensees?
