The best thing as a gamer you can do is not pre-order, AND do plenty of research. multiple sites of reviews, trailers (gameplay especially), the developers (if it's their first game, are they experienced?).

A lot of factors can tell you about a game. People don't do research at all and wonder why they get outraged (like buying Sekiro purely because it was a Souls-like, but being outraged it wasn't like Dark Souls).
