Firstly, please let me say that I LOVE the game. I'm about 200hrs in (trying to reach 500). So far there are only a few things that I feel could improve the experience, which I've detailed below...
Backpacks as items
My biggest frustration with the game is not being able to drop the backpack (and its contents) to pick up later - either inside for safekeeping or outside for extra speed. It would also be a fantastic way of creating movable caches or backpacks for different weather conditions.
Second biggest frustration is the lack of edible flora like berries or root vegetables. The game seems weighted towards hunting which I feel both encourages a reliance on weaponry, makes exploration problematic (because meat smell) and discourages foraging.
More dynamic environment
Third is that Great Bear Island doesn't really feel alive. It's really well designed and full of surprises... but (apart from the weather) it's not dynamic. a) Dynamic obstacles like avalanches, ice melts and snow buildup could make exploration more spontaneous. b) Dynamic events like tree falls, bale fires and building collapse could both affect exploration and make the world feel more alive. c) More small, non intractable fauna like birds, mice, insects and rodents could make the world feel more alive.
These events could happen in real-time for maximum impact or while sleeping for easier implementation.
Increased weather patterns
In contrast, Great Bear Island's weather is really dynamic and I'd love to see more weather types. The mysterious nature of 'the event' gives a little more creative freedom regarding weather patterns but hail, thunder or seismic activity are all believable options.
I'd really enjoy it if there was some danger to using fire indoors. Like the potential of burning the house down and having to move on.
The ability to break down a campfire would be really useful.
Thanks for reading!
