8 is not enough after a month tbh. Neither is 4 'worlds' (especially if some are a combination of the others' environments).
Hopefully "more than 8" turns out to be at least 10 at launch. It's not like you can go play the campaign to mix it up.
I was hoping there was going to be a trend of not charging for new maps but guess that's too much to ask.
It's EA. Also the lack of environments is probably a side effect of spending too much money on the graphics, easier to keep things to the same area than use an entirely different tileset on a different planet. In fact I'm going to guess graphics are the main priority here... Oh well, we'll see.
And yes, the second tweet seems to be a reply. But that's not an official account.
