I think he has a point. TB is one of my favorite genre but I never played any where we can represent "flow" saying : "decisions are made, player imputs appear on screen and enemies react" (quote from Wormerine).
The only "flow" you can have in TB comes from illusions (i.e like cosmetic animations), lack of possibilities (so you don't need many times to choose what to do), and very limited ennemies (so their turn is short enough).
My bad. By enemies react I meant enemy turn. Turn based games have rhythm, and if it rhythm is disrupted the flow of the gameplay is disrupted (like player making decision about reaction on enemy turn).
