@RaeoftheLightThis is as sandbox as the real world is, which isn't that much really. There is soft and reciprocated determinism everywhere you look in reality so the RP will be similar in that respect. The world has some elements of fact and other grey areas for players to fill in.
@DeepestApologyStat system - not likely - I will gauge whether any submitted CS are overpowered and I will tell anyone if their character can be bumped up a little. However, not everyone has the same capacity to learning nor do we all have athletic bodies or quick wit. Some people may simple be more powerful/'stat high' but that doesn't count for much when they make a bad decision or if chance fucks (excuse me) them over.
@MatthiasAngelAs far as goals go, I will be happy to assign and/or suggest some once people have an idea of their character and location. As the RP progresses, things will change and so will the world thus the characters will have to react to this stimulus.
As in real life, chance and difficulty are a primary factor to challenge and ultimate success - by chance their may be a storm during your climb up a mountain but the climb is not too difficult for you, so you make it up intact. I will be happy to throw in some rolls or world actions to be built around.
@LilygoldEveryone starting with nothing will make the beginning posts very similar - not everyone in the world will be extremely poor in possessions, a few items and belongings can do no harm. I can easily notify the players of season and general happenings in their area - though going as far as temperature and weather will be too restricting at first - though I will have no qualms with giving this information for each new day as it passes - should people request it.
I am but one man, so please don't think of me as judge, jury and executioner - your ideas are your own and have been shared - all taken on board. I am happy to work with you all to make something to enjoy :)
Any further points?
Feel free to PM me if you are interested/contributing but would rather others didn't see or you are worried you will be ignored.
Have a nice afternoon.
