I feel like the biggest lie that gets prepetuated is the length of games. There are some extremely short games, but it takes the same amount of time generally. Your average JRPG (despite the silly people that claim it) will take no longer than 30-40 hours. This goes back to the PS1 days. There are exceptions on the short (Rogue Galaxy, FF X-2) and long (Persona 3 and Persona 4) end.
I don't think that a long game should be seen an inherently good quality. I'd rather play 25 hours of greatness than a 60 hour game with lot of dull, boring filler.
