I too like playing DF for the story it generates. But I can't get into playing just ASCII, nor plain vanilla.
I tried last night with 43.04 and it was just a pain to build above ground without it remembering the last block material I need for walls.
Black background with multiple 16 color text is ok occasionally, but not so much for multi-hour gaming sessions. When trying to find the dwarf who will most likely be a good candidate for armorsmith is a pain in vanilla.
DTherapist can use some custom color settings, but I find it far easier to read the deeper info for each dwarf, and micro managing them.
I don't like TWBT multilevel, and it's given me more crashes when I use it so I stick with 2D with True Type font.
I also look at this from a developer's point of view. Sure a 'g' in ascii is enough because time to make it pretty is not part of the game function, so it can wait.
But at the same time, there are ways to change what that 'g' looks like outside of Toady One's time, and it is available. So that option is available to the users at large, it enhances the game for others and the purist can also choose to not partake with it.
Any user can use the starter pack and set it back to ascii and do not need to set it back in subsequent use.
I find it peculiar that some players worry about bloat or extra bytes from the LNP. With how cheap hdd today, I have like 7 versions of DF installed and I'm nowhere near running out of drive space.
