More "background" on Ecco : it's inspired by the works of a crazy researcher obsessed with dolphins, aliens and hallucinogenic drugs, in no particular order. Fitting.
I've only played through the first one, back in the 90s on the PC version. Completed it several times, I had fewer games and too much time back then. That story included a completely straight bootstrap paradox around the middle, which blew my mind a bit.
Years later, I got it and the second one on the Wii, for old time's sake. They aged terribly, I don't have that kind of patience anymore. The shitty wiimote D-pad certainly didn't help, but wow those time-limited barrier eating things and those pixel-perfect dashes through octopuses and currents are just tedious.
I play VR regularly, including some stuff with relatively free movement, but with all the dashes and jumps, my inner ear is going "Nope, no you don't".
