It's this sentiment that I share at the moment, for me looking at all the videos Odyssey doesn't add much to the game to be honest. For me personally I can already land on planets and explore settlements in a SRV. For me it just allows me to walk around in stations and buildings which isn't worth the performance hit tbh
In an act of despair/desperation to hold on to my Elite-gaming-mojo I decided to wipe my main CMDR save and start from scratch (7 year old account, 10bn in assets, FC, everything unlocked, Admiral King, triple Elite yadda yadda) - because everything felt so
pointless, more like a playground where you dip in and out of each separate activity, credits no longer mattered nor anything else. A bit like unlocking training mode in other games. While this was the case already to some extent with the Horizons ship/SRV content, I find it's much worse with EDO, because everything on-foot is ring fenced - mats, engineers, missions, ranks etc. It truly feels like an optional, tacked on DLC which is a shame.
Having said that - now that I started with a new CMDR save it's a bit more fun again, I try not to fall into the grind trap (various engineers have been unlocked but I haven't even bothered visiting them yet) and just wander around trying to make credits as they're finally meaning something again. Still, settlements and the concourses still feel very optional, I could basically ignore them entirely and it wouldn't affect my spaceship-flying game at all. I just dip into them now and then simply because why not.
I preordered EDO based on hopes and (empty) promises so I may as well get along with it for as much as I can, but would I buy the DLC today, knowing what it entails in all its glory/ugliness? Probably not. But it
is subjective, and others seem to enjoy the DLC a lot more than I do.
PS - the walking around in stations/buildings is quite limited tbh - it gets old very quickly certainly the concourses. Settlements can be varied (in terms of their background - the design of the buildings themselves is very modular and once you visit a few you see the repetition, but I don't want to knock them too much - what I find worse is the lack of non-mission based interactivity at them) but the rough performance kills any immersion if you're sensitive to poor fps/frame pacing.
