So the IPO was ended after 27 days? And people had to pay more and more and more during that time? Nxt's IPO was 61 days long and everyone paid only 2 Satoshi for 1 Nxt on day 1 and also on day 61. So Nxt is still 6000x more fair than NEM

Can't go by the number a days, because that only points out how popular NEM was compared to NXT in this case. They had a goal to reach of a certain amount of accounts and they reached it in 27 days. I imagine over 1,500 unique people, and new people that never heard of crypto, vs 70 who were all from this forum.
It's more fair in that a lot more people were able to join.
Part of the success of this fundraising has to do with NXT and its legitimacy, else people would have been more hesitant to join NEM. So this is not a put down on NXT. I was simply pointing out the flaw in your thinking.
