they can write a code for a totally new game in 7 months, but they are busy releasing DLC's
That's the usual forum logic that applies to trolls and flame baiters.
Moderator Action: While I'm not sure your exact intention, this remark seems to imply you are calling out Deep_Blue as being a troll, this is against the forum rules.
DLCs they release are largely art assets with a UU, a Unique building or improvement that requires minimal coding to make it work.
Your AI programmer isn't going to be working at length on the DLC. And your art people isn't going to be fixing a bugged feature from the vanilla game.
And TBH, although I have not yet purchased a single DLC, I have been quite impressed with the work that went into them when I reviewed the DLC previews on steam. Polynesia, Spain, Inca's look like top notch additions.
I'm holding out a little longer hoping they all get repackaged into a future expansion/re-release.
