Now thats what i call a reply, hah :)
Thank you.

If you would like, I will offer my 2 cents based on my work in IT projects. Some of it might be obvious, but you would be amazed how many people tend to ignore the obvious stuff...

Re: increase quality at launch:
As a player I can only applaud you for doing that, however you might want to set strict limits on how much effort are you willing/able to invest in doing that. Im sure you have a vision that you want to achieve, keep in mind that perfection will never be achieved and you need to set a compromise between what you can and what you want (otherwise you will never finish the game and just end up "improving" something that was always good enough to be published).

Re: EA v Full. You dont really have to invent the wheel here and I will provide 2 examples that you can get experience from. The first one - positive - would be "Being a Dik". Dr PinkCake (these porn names.. srsl.. always in stitches :D) opted for seasonal launch with 4 episodes each that are clearly divided and you know exactly when you are transferring from episode to episode (there are summary screens). However there is also a clear and visible difference between the visual quality of the episodes (massive, massive difference between what happens in episode 1 and in episode 8 both in quality and quantity). Season 2 is sold as a DLC for season 1, but apparently Season 3 will have its own launcher, so I am unclear if he wants to sell it separately or as another DLC that changes the launch of the game...
The other example is Lust Theory by Inceton games. Again seasonal launch - but each season is sold as a separate game.
He went all in with the 1st season (including voice acting), but that left him drained for season 2 that is still on "mixed" reviews and is considered "unfinished" by the players when compared to season 1. I would venture a guess that he simply got overambitious after the initial success and then ran out of money. (still better than his "Inside Jeniffer" where he got whacked for terrible writing and mediocre animations).

Regarding the upscaling of quality - I would honestly leave it 1080 for the entire game, so that you can maintain the same level throughout. Once the game is fully out you can then see if it might be worth it to upscale as a sort of "deluxe dlc" or even a free patch if the game does really well ;)
As most devs found out, once you go steam and you do well, there is very little reason to opt for android launch, as the limitations are just too big for these games.

RE: Pricing: You are a game developer, not a charity. You need to make a livable profit..  You might even want to rise the price of the base game higher, but then put out the DLCs (if you go that way) cheaper. Or even adjust it later on after launch. I would say, decide based on how much game time you provide at what quality.

Looking forward to your future content :)
