In my humble opinion it seems to me very well to show the building process, though if I noticed a bit slow in that part of the video. Perhaps an increase in speed makes a difference.
Yes, it does indeed. However, this is not a tutorial. There is no need to explain how to build ways. It is important that it is shown that the player builds the ways, but briefly. Too many details bores the viewers. Put yourself in the shoes of someone reviewing greenlight games:
One gets a number presented by Steam, then one has a look at them, when it is of no interest, just click to the next greenlight game. In such a presentation this means the player has to be kept engaged as long as possible.
Building ways in a tile based world was new in 1990, in this way since 1994 (Transport Tycoon) this is expected behaviour.
It is very good that the videos now stick with one pak, pak128. Only at the end others are shown, as examples for the variety. It is important not to confuse, by changing not too many parameters at a time.
I love the comparison of 'small world' to 'huge world', that is fun to look at.
Does this also mean that it is decided upon that 128 will be the default pak for steam? Or would you change that for a final version, if required (e.g. if pak 64 were selected)?
Some people on the forum did fairly good voice overs to their videos, do you think it were beneficial were there voice, not only text? For example James' videos were quite whimsical, since he imitated the ideosyncracies of old British educational videos.
