This is probably one of the better done "wars" I've seen in a manga.
Yeah, it ended with "the power of friendship" but the main character was pushed to do it and his previous adventures and encounters were taken full advantage of. Nothing was pointless and because of that I could overlook something as small as "power of friendship" ending. It wasn't a one-sided war, there were loses on the good side, they were pushed to the brink.....umu satisfying.

lol, I honestly can't disagree with that statement despite feeling there's more to it than that. He understands that the AI is TOO good in the game to the point that in this world.....everything is the same for them as reality is to the MC. But yeah, he got too invested emotionally to the game.
