I bought it cheap for me and my buddy at some 2 for 1 sale and now I'm ashamed :upset:
Why would you be ashamed of playing one game or another? The only reason i came up with is if it was a scam, a ripoff or was very offensive. If a game caught your attention, it doesn't matter if it had poor gameplay, bad graphics or was incomplete.
Well one other reason is if you never played if after buying, but that's a number of games i have in my Steam library, although i would never say any of them were one of the above i mentioned. Additionally, some "bad games" get better after a few updates (if they do get updates) and NMS gets them. It's a way different game than it was at release time, not to mention the story it shows in the main quest line is very intriguing (Artemis quest line). I never did get too far with the main story, although i aim to at least get to know it better. I think i'm halfway past it now.
So yeah, wouldn't say the game is boring or there isn't much to do. Surely there is some grinding, but with the latest update you don't have to run back to base so much as most resources stack up to 10k instead of 250, while other items have diverse stacks (lost tech 25, but doubles in backpack storage, etc.). Also, depending how you play and how much luck you have at the beginning in finding a good weapon/ship (with lots of space for enhancements and loot) you'll have a varied experience now, yet less frustrating than before.
And no, i wouldn't buy it for 60$, not even for 30$. 7DTD, i'd gladly pay some more if a need arises, just to show my appreciation. Although perhaps 30$ at most.
