I reinstalled the v4 generator while my friend was using it and...oh my goodness, it's so simple and clean. I hadn't realized how much I missed it. If I ever do just sit down one day and go 'screw it, I am writing a game and I'm writing it NOW' I probably will just use 4. I love what 5 can do in theory but I don't like to lose momentum fiddling around. I7 just increases that problem tenfold. The only thing I've ever done with I7 is test out how to do very simple and basic things that take about two seconds and no need to touch a manual with ADRIFT.
Forget spending 90% of my writing time trying to figure out how to make things work, if I ever start a new IF game I'm throwing all the text down into Scrivener and then just copy and pasting it all over at once and stapling some tasks on. Boom, a game. Done.
