Should I start playing again?

Hello everyone! I played ESO over a year and a half ago until my PCs motherboard broke down and I had a ton of tests etc. now I have more spare time and little to use it on. So I am wondering; should I get into the game again? What has changed? How large is the game file itself?(my new pc is already kinda full and emptying up space is always an adventure in itself), what's the current state of the game? What do you think? I believe I was no longer able to play at the time of the (was it thieves guild?) patch release.
