Uh.. YES? They had AAA-quality CGI reveal at E3 2015. It got a LOT of people pumped up. Microsoft execs were saying it was going to be a new cornerstone IP for the company.
Why do you think so many people were confused when it was announced as a "value priced" title at only $40. Microsoft were spinning on their heads trying to explain how that didn't mean it was any less of a game, although that's exactly what it ended up meaning!
"Why ReCore is $40?"
"We wanted there to be no barriers. We wanted to be able to give you a great AAA that gives you $60 of value but if you aren't sure, not let that be the barrier of a tradeoff of, 'Hey there's a $60 game and there's this game.' We wanted you to be able to get in."
Aaron Greenberg literally spinning on his head saying ReCore was a AAA game when he knew it wasn't even close to being that. Outright lies.
