Im not developer, but I can answer some of your questions.
- Is this open world or a single player story focus mode experience only ?
Its definitely NOT open world. They never said anything about open world. Its not linear either, there is some branching, different solutions, different endings, but its very story focused.
Open world is overrated anyway.
- Can i change from first person to third ?
Its extremely unlikely that you could do that. For a good reason. It should be horror-like experience when set camera is important to achieve the effect.
- Are this the only game you will create from H.P Lovecraft universe or we'll get some sequels?
Who knows? Maybe if this game will be successfull...
Of course it could be all totally made up, although Spiders did say they were inspired by 17th century Europe. In fact, the whole thing minus the magic tree creature reminded me a little of this movie scene.
I doubt that colonial (invading) forces in this game will be depicted very simply as "the heroic ones" while naties will be "the primitive ones".
I think its more likely that natives in Greedfall were partially inspired by Aztecs.
Are you sure about level scaling? In Bound By Flame all enemies are hand placed and jump in difficulty significantly only when advancing story chapters/locations.
It doesnt matter that much. Main problem is hard respawning of everything together with a lot backtracking - that is bad design IMHO and big NO for many SP RPG fans. I hope it will be lesser problem in Greedfall because of bigger world and fast travel system.
I have a small fear of the deep dark parts of the ocean and was wondering if this game will feature any parts where we will have to go down into the dark parts of the ocean perhaps even to the city of R'yleh. To be honest the fear of the ocean will probably make this game more exciting for me.
Well, it depends... I wouldnt expect R'yleh or some kind of free diving in the ocean. That would make scope of the project much bigger. I believe there will be some interesting hallucinations or visions of the deep ocean. Maybe there will be one or two ominous dives in gameplay too but it will be scripted. So we will see. There could be dives in the deep but I wouldnt expect diving to be big feature in gameplay.
I noticed there were 2 main problems in Technomancer that players complained about - backtracking and constant respawns. Greedfall should have fast travel so I assume that backtracking wont be an issue here.
So lets go to respawns. Dear devs, pls will you correct this ïssue in Greedfall?
I know a lot of RPG fans who were more or less disappointed by Technomancer because of constant respawns and will be much more intested in Greedfall if you correct this problem. Its very tedious and boring and you have feeling like you achieved nothing (no impact on the world) when every enemy quickly respawns again. This is not MMO. There could be some places where respawns make sense like guards in town (there are more soldiers than those you see on streets) or some big lair of beasts, but pls dont do respawns everywhere.
One preview claiming "there are no fetch quests in Greedfall"
Im not sure if there will be any characteristics like Strength, but so far it seems that those skill groups mentioned in my first comment are pretty much correct.
Social skills - Small Talk, Persuasion, Intimidation
Profession - few detective skills like Investigation, Spot Hidden Things
Knowledge - Forensic medicine, Occultism
Physical skills - Lockpicking and probably few more ( Break (into) something ? )
Of course, it could change but I would assume that it wont change very much.
