> best to star with small projects, but finishing them is not always necessary. I've done lots and lots of different test projects over the few years in C2 and learned much about streamlining things and how to make the project easier to control in the grand scale.

yes I understand but that's not what I mean. When you actually finish a game -- completely finish and put those finishing touches on it. That's when a lot of stuff you never knew about comes out to play. When your core gameplay is complete and you get into the overarching gameplay, level design and "packaging" of your game, there's a whole new level of development that needs to happen.
Like 
sqiddster was saying about performance issues when you put the whole polished game to the test on multiple machines (playtesting). And other things that come out like, "The Next Penelope" not being able to stream on Twitch and some other issues with captures because of HTML5 etc... or Save Game data, or Leaderboards or Greenworks etc... it's definitely not easy!
There was a point where I could easily capture footage using Fraps/Node-Webkit for my C2 game project, but that seems to have broken in recent releases, capturing a black screen. Do we even know if it's a NW or C2 issue? Prior to that even on the slower machine I take around to events for playtest (dual-core i3 microATX), I had no trouble getting 60fpx at 1080p while capturing audio/video footage.
