The reason we don't have additional planetary maps for open testing is they aren't playable currently. We're working on the framework we currently have and will be making sure that's quality before we expand into other planet types.

Well yesterday the new dev blog got released with here and there some fancy informations. But i can read between the lines.
We wont be aible to fight on Lava, Aqua, Burren desert, Gas or Ice Planets. Why? Well because of this:

We will fight only on temperate planets which is in my opinion kinda sad. I woulda had loved to fight on different planets. I simply blame the devs lazyness for this to create different looking battlefields.

I will tell you how this is going to end up on EVE:
Every eve player will find out which planets are temperate, reinforce them to the max so that they cant be taken and thats it. Usually each system in eve has 1-2 temperate planets and thats it.

A system will fall with those few planets without counting in the others. Im dissapointed cause we probably could fight on the other hostile planets due to our dropsuit which allows us to survive in life threating enviroment.

Can i just point out

it costs $500,000 just to add a new char as DLC to a side scrolling 2d fighting game "

it is estimated that each marvel vs capcom hero cost $1 million US

so then you have to stop and think
this is a 3d game
the game is FTP -with the option to pay for more stuff but not every one will do that

they have to pay for the games servers
they have to pay people working on other projects
they have to pay the creators of dust

im sorry mum did not supply ccp with the millions needed to have a massive team of people working on the game just so it can meet YOUR release day and be on time and up to YOUR expectation's which have possible been set by the standards of other triple A games that already have millions in funding before they even consider making a game

even after all that you want then rushing to make new maps when they already have issues with the maps now ?
like oh hey im walking up a hill

STRAIGHT THROUGH MY SHIELDS AND HALF MY ARMOUR
that's fine
let's just focus on maps these are issues that don't need to be focused on we clearly need to add more stuff and hope it does not make a bigger mess

(that is what i think every time i think ccp should add something to dust)
and if you want water GO FOR A SWIM IN ONE OF THEM POOLS AND STAY DOWN THERE
(yes there is water in dust and yes it does kill you)

*edit*
The Skull girl char cost only $150,00 as i had my numbers wrong
but i quote
"it was estimated that each marvel vs capcom hero cost about 1 million to make"

(here are the details of the pricing for making the skull girl dlc hero)
While $150,000 does seem like a lot of money for a single character to be added to the game, Lab Zero Games has broken down exactly where the finances go.

$48,000: Staff Salaries GÇô 8 people for 10 weeks
$30,000: Animation and Clean-up Contracting
$4,000: Voice recording
$2,000: Hit-box Contracting
$5,000: Audio Implementation Contracting
$20,000: QA Testing
$10,000: 1st Party Certification
$10,500: IndieGoGo and Payment Processing Fees
$20,500: Manufacturing and Shipping Physical Rewards

i dont understand why the instalations are always in the same place on these massive maps we have. letting them rotate would give allot more variety, or does this already happen and ive just not noticed?

CCP can't throw everything out at once. It's not like they have a magic dev team that can do everything on a whim. There needs to be planning, testing, evaluation and then deployment. Everyone needs to calm down and let them do what they do. I too would like to fight in exotic environments, but it just wont happen right off the bat. It is coming though.

CCP is throwing out nothing at all.
Now restart your excuses.

they have said that they had done some in house testing of cloud cities (guessing gas planets, which I'm curious how we aren't instantly crushed under their gravity), but it was far from anything they would consider having yet. Just get the basic temp planets out there and see what bugs pop up, then add more types as time goes on.
