If you're into exploration, then IMO it absolutely will be worth it. For months leading up to Odyssey's release, I was dead set on pre-ordering Odyssey the moment FC interiors were announced. Sadly they never were at the time, but I did end up pre-ordering anyway 2 days before release so I could play around with it while recovering from some recently-acquired injuries.
I believe I made several posts about my 1-handed SRV driving adventures back then.
Ever since it was announced that Fleet Carriers would be personally ownable, my endgame goal for Elite has been to park my FC over my first earthlike world and use it as a base while I fully map the surrounding area of at least a 50ly radius. By the time I acquired my FC, Odyssey was only 6 months away, so I figured I'd wait for that before heading out.
Once Odyssey released, I did in fact take my FC out there, but it quickly it became apparent that a FC without Vista Genomics wasn't gonna cut it. Going for joyrides in the SRV is one of my favorite activities in Elite, and the only risk form doing that in Horizons was losing the SRV itself
(which I why I always carry 4). But now, one SRV crash and all your biodata is gone, which I knew would be too great a risk to take for any serious long-term expedition. So I went back to the bubble and postponed my expedition, in the hopes that someday Fdev would get around to adding FC interiors with Vista Genomics as an optional service.
Lo and behold, we're now less than a week away from realizing that dream and I couldn't be more excited. Not only are we getting big things like Vista Genomics and viewable jumps, but we're also getting a bunch of smaller, understated features that'll truly make the FC feel like a home base out in the void. I can't wait to come home after a long day of exploring, turn in my biodata, and have a drink with
my actual carrier crew in the bar. Or just chill in my ready room, overlooking that beautiful, pristine earthlike world out the window.
