Actually I've been doing consistently worse in the years I lived through than the rest of the timeline. Apparently the older I get the more styles blur together. I tend to estimate ~5 years too early for the 1980-2000, and ~10 years too early for 2010 to present.

Interesting, unless there was a major clue, I've had as much pain in both cases.

I always got the most points when I just did a completely random guess haha. Taking the actively misleading part out of the equation.

I was finding that I had a harder time with very recent photos. Fashion has become a bit static perhaps.

I found 1973-1997 looking very similar in color film quality, and cars on the street. maybe if I was more familiar with models, maybe.

it was only obvious it was 80s or 90s if something silly was going on.

my top score is 2900 right now

Changes in consumer-grade photo quality between 70s/80s/90s are actually quite visible if you've looked at many of them. It's subtle, but e.g. newer ones have better range in brightness, i.e. less overly bright or dark areas in high-contrast images.

I got a bunch of Edwardian—WW2 photos in one go, and netted 3190. I might be able to get higher than that, but only if the photos predate 2000.

I think styles changed a lot from 1900—1970. After that, things are pretty hard to distinguish; retroactive clothing styles muddyvthe waters.

got 3632! and now my watch has ended

First time 2200.. what a fun game. I'll use your 2900 as a goal

One of the photos was labeled with the year, and the game identified it differently. It's all in fun.
