I tried Caravan... it's too confusing to me. I've read some guides to it several times and it still boggles my mind.
I play it. I like it. That said … never has an easier game been more confusing to learn. This is in no small part due to imprecise pc controls and lack of clear cut instructions.
150 hours in second play through:
Don’t use drop boxes
Other than the two for radiation and stimpaks, no drugs
Various weapons have gone unused/undiscovered
No ammo crafting, cooking, campfires, or use anything that’s not ready to go
Never thrown anything but a grenade
Skipped various side tasks/quests that are clearly: run here, do this, run back, now run somewhere else …
Never eat or drink (sleep a great deal though)
Have not recruited all the companions
Haven’t called for help on the NCR radio
Had no use for Powder Gangers except as target practice
Won’t shoot first if I have high enough speech to resolve something peacefully
(Powder Gangers excepted) I never damage my reputation with a faction before getting close to the end game
And : rarely use melee weapons, energy weapons or fast travel
