User blog comment:Latias1290/(Poll) How fast have you ever made progress?/@comment-24557896-20140225020115

It all depends on how you're playing. I've gone from start to hallowed set (prior to 1.2 it was the best) in like 16 hours, but it was somehow a "rush" to get top items. Today I like playing slow and get all items instead of jumping to the best. The character I'm using to enjoy new contend I have since july last year and I remember it took few weeks to get top stuff(before halloween update came) thanks to lots of farming, etc, but it's my favorite one since I have any armor, vanity, weapon or acessory item I might imagine wishing to use.

If you try to rush the game and get all best items(acessories included) on current version (1.2.3) it should take a week or two. If you wanna know how fast you can get into hardmode, it's probably around 3-5 hours depending on your skill and, of course, luck.
