MC didn't OP for no reasons.
1. He had tons of experience in the game before the real world turned itself into game. That meant he got used to losing and dying in game more than anyone else.
2. He could remember the essential elements and details about this games, and he was a professional player before. Of course, he should know well how to use his knowledge in adaptations.
3. His personality was not cold-hearted for nothing because humans treated him poorly first from the beginning.
4. It was not exactly easy for him to gain power!! Each power, item, and skill that was given to him by the system was created from when MC met the conditions or hidden quests. Those conditions came from his copying skill while those hidden quests came from his own memory that got important information to be used at the right time to the right place.
5. If I were him, I would agree about hiding his own secrets and identity just to be save from human greed and envy too.
