I'm very late to a party i would have really enjoyed with this thread but skimming through i have to say to OP, your asking the right questions but to the wrong people and with the wrong expectation.
based on this and the 6 other threads you posted its clear to me your trying to do something called "sampling", thats when a new company or service go to a crowd of a likely interested group of people, tell or show them a product/service/idea, get their OPINION, and then tally up the similar opinions. the easiest idea of this is when you go to the mall and a place in the food court offers free samples and ask if you like it or not.
to me this works best when you have an actual product or demo in hand as far as game devs go, but even then you, as a game dev, are asking other game devs what would be best for the PLAYER experience.
thats like Atlus (creators of persona) going up to Square (Final Fantasy) & CC2 (Naruto/Dragonball/ .Hack) and asking them which graphic style is more appealing for players, cel shaded 3D or full on graphic card breaking semi-realism 3D with top tier particle effects. Atlus themselves would admit they like cel shading and CC2 would agree but Square would say semi-realism. Now what?
I say you should start making your game, maybe try building a little circle on instagram and other social media pages where your more likely to find other PLAYERS as well as Devs and when you ask your questions, simply tally up the opinions, if 10 people love exploration and 3 people hate exploration. then by jolly you might want to include some exploration. but always make sure YOUR vision for YOUR game comes first, don't tack things on that YOU don't like because you will put 0 effort into it and it will show.
