About low fidelity 2000s games with weird and janky gameplay but trying to pioneer things, I'd like to suggest to Ross Omikron: Nomad Soul.
It's a very good game, or at least I liked it a lot as a kid, despite the jank (which was even at the time completely perceptible, much like Messiah).
It has European sensibilities and storytelling, some outdated tropes, David Bowie, a lot of ambition, and, weirdly, possession!
I looked around to see if someone suggested it and couldn't find anything, so there. If there's a better place to suggest things, please let me know.
