I don't intend to let FotG die unreleased
I've mentioned this a few times on Discord, but 2017 was absolutely nuts for me at work and was very busy for others in the team.
As far as progress goes, there's 31 issues logged in our mantis that we want fixed before public release, 10 of those we want fixed before a beta release. (So far, more will probably appear of course!) There's a mixture of playtesting & fixing campaigns, merging code to FSO, scripting fixes, model updates & fixes (e.g. debris, lods, missing maps), making some of the in game cutscenes more exciting, updating HUD shield icons, etc. There's too many skillsets required for a single person to complete this alone, but hopefully the team can get some time this year to make some good progress.
