Curse the Mainframe! by Rxel is an atypical system story. It follow System No.00290596 (Or Alec, as he is named after that) in his punishment.
Alec was the perfect system. Sending his hosts to be the protagonists of their worlds. Following the rule book to the letter. No privilege or bonus given.
But well... as we know, systems that are liked are the bullied kind and those who twist the system's rules a little for their host. So our system is disliked. Hated even, by his hosts, so much that he gets enough bad reviews to be punished by the mainframe.
So our indignant system was punished to be reincarnated in one of the system's worlds.
There he encounters many opportunities of protagonists... without being one himself.
We have to know that Alec is a system that lost a lot of his humanity. His comportement is more like a machine, without compassion for his hosts.
So his punishment actually lead our antisocial Alec to regain some of his humanity.
What is good is that System No.00290596 is actually influenced by the world he is in and really become Alec, the person he is reborn as. From the simple fact that he is Alec, his personality begin to change.
So you may ask... why is he a system ? Couldn't he be just some antisocial human in some world ? Well, the fact that he is a system has a real influence. He views the world as a system.
And... He IS a system. Who does the job of a system. It gives a whole other dimension to the novel.
(SPOILER ALERT ::
Just wait until he obtains 1000 system points, you will like it ;) )
That was for the story.
The world is developed little by little, without big chunks of explanations. The systems of magic and the organisation of the social class is also interesting :
Each person has his social class defined at birth. Even if you are born in a clan/sect or big family, you can still be trash at birth, or even worst, a criminal.
The MC is also powerfull. He isn't OP, but he was still a system for some centuries or so, thus he has both intelligence and experience, which gives him quite the head start. He also has his own personality and isn't your generic MC.
The side characters are also interesting, the stories doesn't focus much on them but doesn't disregard them either.
Grammatically, the story is also well written, I didn't find many faults. The author has written quite a few novels before that, so you can expect some quality.
In summary, it is a good system story that I warmly recommend.
