It seems a bit in conflict with itself me, so far (I'm in the middle of chapter 4, to give you an idea)
On one hand it does seem interested in its own world and story, and having an atmosphere unique to itself. And on that level I can appreciate in in the spirit I feel like it was promoted, as a sort of lost LucasArts game found in a drawer.
But on the other hand, it's a game about LucasArts games, with all the sort of reference explosion that implies.
The struggle I'm having is that I'm enjoying the first thing it's trying to be much more than the second thing. And I don't know you can do the second thing without compromising the first thing.
Like. I enjoyed that new Chip 'n' Dale film. I think the references are funny, and it does its job as a meta piece about chip 'n' dale and animation in general. But I also watched the trailer and knew that's what I was getting. If I thought I was getting an old school Chip 'n' Dale adventure, I probably would have come away confused.
Watching this trailer I could be forgiven for thinking that TWP wouldn't be SO much of a reference explosion as it turned out to be:
That said, I do think the style settles down toward the middle of the game and it gets a bit more comfortable with telling its own story.
And now, because this has drifted from ReMI for too long, what I will say is that they do seem conscious of this, and I think they will have spent a long time figuring out what the tone of MI is and where its meta-humour fits in with the overall style, so I'm not so worried there.
