Ron Gilbert said, that when developing Thimbleweed Park they chose the retro graphics because they wanted the game to be retro. And this whole game cries out RETRO.
Now ROMI is a totally different approach.
They use new technology new art to tell a new story.
It always was like that.
When you look at each LucasArts adventure they always used a new style to tell a new story, be it Monkey series, Maniac Mansion 1 + 2, LOOM, Indy series,
Full Throttle, Grim Fandango, you name it. It always was different.
And also always looked fresh.
And there also always have been people who didn’t like a new style.
I e.g. could not get warm with CMI, but mainly because I missed sth was not there any more after Ron left.
But that thing is back again - I felt it when playing Thimbleweed Park - and I am sure it will be in ROMI.
So I am pretty sure it will be great.
