Yeah being able to change things up whenever they want was a pretty great idea from the mangaka. It keeps things pretty interesting too. I really liked the mini arc they had for that mecha VR game for example.Honestly, favorite thing about this manga is that it's not all about the one game. Sure, it mostly is, but Sunraku's pretty well established to play whatever he wants in the early chapters and it's sweet that the author makes sure to keep that up as they go along.
Another effect it has is that it shows the readers where his skills come from. The readers get to see the extent of his skill rather than just being told he has skill.Honestly, favorite thing about this manga is that it's not all about the one game.
