Inno keeps getting side-tracked, that's why. She strikes me as someone who just winds it instead of having a carefully thought out plan and time frame for things. She starts working on one thing, realizes she misses X or Y, or this sudden idea pops up in her head and she wants to add it, or something needs to be tweaked/revamped because it no longer pleases her or fits her future plans, etc, and it just snowballs from there.
We were supposed to be done with Dominion/Submission and move on unto the Fields months ago. She has stated before she prefers to work on the mechanics of the game because those are easier to implement/tweak than writing blocks of text (which is basically half the game there...). At this rate, it feels like she's just delaying the inevitable. In other words, she wants to add a thousand little things that bear little significance at the moment (feature creep) rather than working on the actual meat of the game and moving things forward.
I don't mind having a ton of content in the first two areas of the game, but I'm also worried it will end up like TiTs. A ton of stuff in the early areas and a drought spell later on because all of the good stuff was used to fill in the first planet or two. Seriously wish she would work on more mod support...
