I'm pretty sure most engine-features unlock after you gained a certain level in that game-area, not after you played a certain amount of time.

The first extra batch of features is unlocked after reaching level3 in that area. For example lv3 in level design will unlock the level editor, level3 in dialouges will unlock better dialouge.

I will try to make a list on my next playthrough.
