Overall it's a fun idea though. I was able to consistently get pretty close in time and location so even with the anachronisms there was enough there.
This is an example of something that looks like an educational game but has the opposite effect. I had fun doing my round, but I won't do it again, because I think I will learn more wrong things from it than right things.
> This star-lit scene in a [...] garden showcases [...] using a seven-foot reflecting telescope, with speculum metal mirrors, in 18th-century [...]. The [...] row house architecture, oil lantern lighting, and his period attire all pinpoint the late 1700s. The meticulously ground mirror indicates the telescope’s custom design that enabled this revolutionary astronomical finding.
The result is a picture (with some panning animation) of a guy who for some reason has a pistol in his belt, looking through a complicated-looking telescope that is however definitely not a seven-foot mirror telescope in broad daylight with an oil painting inexplicably hanging in mid air behind him. No starlight, row houses or oil lanterns to be seen.
That said I too was a bit annoyed by how it rendered the byzantine empire. I thought Carthage was meant. So i was over by a thousand years.
