How big is the TERA file supposed to be once it's downloaded?

The download itself is around 20GB. Uncompressed this will take about 24GB on your hard drive. If you're worried about disk space you will probably need ~50GB of free space before you start patching so that the compressed files have space to unpack themselves.

4 days still downloading, 53% so far, starting at 1 am til 6 am every night. Satellite sucks. But it's all I got.

About 1 hour for me, but then again I work at an ISP

45 minute download.

Jealousy is not an option.

Yeah it only took me about an hour and a half to get it fully patched lol. Jealous?

to me the game says 2d 20h @.@ LOL

380kB/s and at 6% right now. fml, I have 15 more hours left. So yes I'm jelly. D:
