Personally, I don't mind the screwing-around-with-stuff videos, but they are not a substitute for a real feature introduction/preview video. If there is any messing around in those videos, it should happen after all of the features are given a proper introduction and (if applicable) how to use them is clearly shown. Otherwise, you're just wasting the time of people who don't want to watch some guys warping back and forth between gates making jokes and Spaceballs references.You see, I'm in the same camp as @therimmer96 and possibly Ithirahad in that I dislike the whole 'we're screwing around, ha ha!' videos. But I understand that a lot of people do in fact enjoy those types of videos a lot, and they bring in some new blood as well. I also understand their relationship with the developers. We don't all have to agree on the same things.
...Regardless, as for the galaxies themselves, I like the 200-sector one, since it isn't too implausibly huge to cross, but it is also large enough to feel like a galaxy. The ones shown in the video just seem... tiny. :|
