I'd say I'm on board with 3 as well, and leaning 4, just because I'm a sucker for gradual and continued incremental changes and dress-up possibilities. Two years ago, it was exciting just to read about the prospect of Twilight's stats changing and the possibility of sprites adjusting over time, so if you put incremental changes out in front of me, of course I'm going to say we should go ahead with it.
As before, I don't mind the extra work involved in writing for additional scenes. I'd have been on board with Twilight's dialect changing in accordance with her stats going up/down, but I figured that might be too many micro-adjustments even for me. This is a welcome challenge.
