It's hard to enjoy when the MC has no reason to be hiding his power. From what we know he could wipe the planet if he wanted to, but revealing his powers to save people is "too much if a risk to get involved with politics" which he does so anyways.
If only the author made MC a normal powered guy who had to adapt to this new life, using skills and systems from the game to try to:
1. Find comrades.
2. Figure out why he's here.
3. Find purpose.
Instead we get an action shounen with no tension and just one dimensional characters with weird ass dialogue (but I guess the reason is that they're game characters?).
