Those times are way overstated as gameplay, because I usually leave the game running minimized when I switch away from it
That's my experience, which I thought I'd mention for anyone who's not aware of that potential reason for inflated times. I remember seeing on HowLongToBeat.com that my Steam playtimes were 5-6 times longer than 'normal', and wondering if my slow playstyle and penchant for wandering off on tangents and experiments was the whole cause.
How about you, are your times accurate or inflated?
Do you know of any other gotchas in the recorded playtimes?
