22 minutes a about 7 minutes longer than what I was hoping would be the average for players. There are definitely ways to optimize you mining for a faster time - and it might encourage a second play through (along with coming up with another mech build, and possibly fighting the other 2 mechs) since you now know the systems better - but as you're not a fan of the genre, I don't expect you to want to play it again - but I'm glad that you did even though you don't like the genre. I was hoping the mech building aspect would help appeal to a broader audience and looks like it has succeeded in my book.
Thanks for playing!
