YTLAG has a very different vibe to it, for a start it is far less naratively driven and more event driven, you get multiple days where you get to pick which activity you go for, giving it a semi open world feel. In TMC the story continues regardless of whether you accept or reject the Mirrors Transformation (the only slight exception being that if you don't engage with the changes you can get a neutral or bad ending), also the MC of YTLAG has way stronger chad energy than Ethan, and is much more isolated due to not being able to share his plight with friends, where as Luke and Sam have your back big time. Not saying this is a bad thing, but (for me) it makes the two stories very different.
