It looked fun but hardly best game at E3. I think ashen and super lucky tale looked much better. But that's because I'm old and love platformers.
And yes it might be a remake but shadow of the colossus is going to look amazing on big ass tvs. Just imagine walking into Best Buy and browsing the tvs on display and that game is being demoed on it. That and god of war will look stunning. They already do.
Mario odyssey also looks Amazing.
Anthem, Metro, and wolfenstien also were beautiful.
But yes there were way more games that looked better than sea of thieves. Sorry :(
