Terraria seems like it would be more of a long-term thing than a short-term thing. Imagine if it made you restart at your start point all the time, regardless of how much time you have in that Walmart check-out line.
Redigit just implemented a new liquid type, and he believes it's "quite fun." I wonder if it's some sort of ... ... well, .. ..
you only wish it was this.
Red also stated that he has given players at least two new reasons to visit the jungle biome.
Now this is actually very exciting to me. The only reasons I ever went to the jungle before-hand was to get the Ivy Vines for the ivy whip, and to see which direction the Dungeon is in.

Oh and to potentially look for either the Staff of Regrowth (Which I have a certain fondness for.) and for anyone hog-tied that I can rescue. The Jungle Armor is too costly to make, and isn't nearly worth it, I think.
