This mod was created for one reason, and that was to be a feature-complete port of 1.7.10 NTM and that's what they set out to do. Originally forked off the buggy mess that is Alcater's NTM:EE, they managed to optimize the main features, as well as get the content correct for once. A huge problem that appears in the forking scene is that developers will usually add their own fluff, some good, some bad. This dev team, on the other hand, made sure to keep in line of bobcat's vision.
There was a lot of original suspicion of it when it was first being talked about, due to most forks/ports being absolute failures. When I first heard of it, I had the same thoughts. However when I did spend some time with it, and even talked to the developers about it, I grew a lot more confident of what they were accomplishing.
Now to answer some questions:

What makes this different from Alcater's NTM:EE?
Contrary to popular belief, Alcater added a lot of useless and half-baked features in his port. Good examples of this was the cross-contamination mechanics (when carrying a radioactive item, it would spread radiation to all of your other items, causing a lot of performance loss), contaminating drop (added a mechanic where dropping radioactive items would destroy it and spread radiation, being more of an annoyance if anything), nuclear cats (????) for some reason, etc. Not only that, but the framework it was built off of was extremely poorly optimized which caused all sorts of lag and tps issues. What NTM:CE has in comparison is a lot more comprehensive progression, with an entirely new weapon system, all sorts of new machines for each tech stage, extremely fast nuclear explosion optimization, and more.

1.7 VS 1.12.2
I feel like I need to mention about this at least once since it has been extremely prevalent ever since Golem left development of the reloaded port. Basically ever since the original porters left, and people like Alcater took up the scene, there has been consistent conflicts over content and differences between the versions. When I saw the success of NTM:CE, I had a very naive assumption that would finally end the conflict, since it is basically 1:1 with the original. However, there seems to be a lot of angry sentiment coming from both the NTM:EE community and the NTM 1.7 community. On the NTM:EE side, they are frustrated about the removal of alcater's changes. On the 1.7 side, they seem to believe its outdated. I'm not even fully sure where this 1.7 sentiment comes from, as when comparing the two there is very little difference in content. There are two reasons why I think why this poor NTM sentiment still continues:

1. Some of the NTM developers for years have always tried to claim that doing ports past 1.7 was impossible, and any attempt would be either out of date, or include ridiculous features. NTM:CE contradicts this and rather than shifting their perspective, they are still in full belief it is impossible.

2. Since these fans usually spent a lot of time in 1.7, they end up getting attached to that version and struggle to consider doing anything outside of it. Normally I wouldn't care as that's their opinion, but these are often the same people that share blaring misconceptions about NTM:CE and often times try to poison the well regarding any information of that version.

NTM:CE Space?
One of the few good forks that came out of the 1.7 sphere was NTM:Space, and often times people have asked about space being in NTM:CE. Luckily, with there being less restrictions on 1.12.2, there is the ability to make your own addons. One of the devs behind NTM:CE has been working on making NTM:Space its own functioning addon, with some success. From what I heard its still in development, however playable in survival.

Conclusion
Mr. Norwood and his team have done an immensely well job porting NTM over to 1.12.2, and I wish them success with their other ports like with MCHeli:CE. I started playing NTM on the reloaded port back in 2022 when Golem was still running it, and when he left, I always hoped that there would be a faithful continuation, which is finally what we have now.
