I love the whole idea of the growing camp with more and more "camp followers". This has huge potential as the game progresses. It gives the player a home base and place to hang their hat- a crucial element to any exploration rpg, and the concept of "getting to know" your companions there in camp is an addition in content that DOS II sorely lacked.
On my first run through, I was conserving spells and trying to last as long as possible in the wilds to avoid "Tadpole time" as much as possible, as others mention. There does need to be something to encourage players to use camp often, because there is logic to the idea behind not wanting to "turn" and trying not to sleep more than one needs to.
It's easy enough to think of ways that camping can be encouraged. No doubt many of these are already planned and underway by Larian.
1. Crafting/cooking tables/stations will go a long way towards making camping obviously important. Larian should make outside crafting tables rare or non-existent to players.
2. A very fun mini-game in camp, be it Orcish poker for coin with the Bard or something else absorbing that would add spice at home.
3. The ability to decorate Camp with heads, trophies, etc. to make it your own would really mark it as "yours".
4. Meaningful XP for Camp interaction with your companions would entice some players to rp and be in camp more.
5. More threats per square foot outside of camp, (which DOS has), adds up to more camping.
6. All that crafting paraphernalia and copious ingredients needing picked up and hauled around will bring folks to camp more often.
7. XP for crafting, which has to be done in camp, etc.
8. It appears that the basic bones of the camp might be designed for rebuilding the ruined building that sits on it for a future lab or other more advanced facility. That would be great!
The Camp is one of my most favorite things in the game. Kudos for the devs putting the time and effort into it. In most games, homes are afterthoughts that receive minimal attention and are among the last things that receive real design thought. Here is a rare game where your home is integral in the actual progress and characters of the game. Good stuff!
