I think it have to be determine by the game. VN game I would say it need to at least 3-5 scene transition from getting to know the character and the plot. Some of them does drag on the story. But sandbox I usually go "if it happen it happens." Since those are more controlled on when you want to...
Does text base game consider 2d? if so I like 2d more since more creative stuff had been made in 2d by small creators. 3d with small creators is a hit or miss. Mostly miss in my book.
Hmm I normally hate having to mention I'm a lurker. usually here for mods and would reply for games or stuff I'm interested in. Usually get on forums once in a blue moon.
