I play gregtech for a long time, but I never been this far before.
I used to play pure GT (3 and 4 I think), and get bored and quit after a reaching MV a few times;
I always wanted to hit endgame on GT, reached MV again, and then Greg stopped GT5 to work on GT6, so I gave up; Then, Blood brought those end games machines back, and luckily I had my world saved yet, so I continued, and this time, think I will reach endgame.
I have a tons of hours on this save, but I knew very little from this version when I started, had to learn a lot. I integrated other MODs, learned to automated things and let my PC on to progress, as without a live server mindset, you get bored and give up after a few hours.
Now my goal is to have an steady fusion, too. Probably, after this I'll stop to play for a while, and start to play some games that I bought and are getting dust.
Then, I'll probably come back to see the new things Blood is adding, and start a new world. (or maybe a server, nerver played online before...)
Seems that GT6 won't be done on next 2 years :D, so I have plenty of time, until I have to learn everything again...
