17 games?! jesus does order matter in em? I'm way late to this party
lmao XD hahahahahahahahahaha ye that was my same reaction when i found about this, but hey...
this only means we got SO MANY GOODIES to enjoy!
XD
as for order... well... the dawn of kagura series, named in japanese kagura reimeiki are simpler games like these 3 that shiravune released, bunch of dungeons, h scenes, gets the job done, in those the order does not matter because they're isolated stories about the shrine maidens, no important chronological order
thing is, most of these girls originate from OTHER games which are more like full-blown SRPGS and do have more fleshed out stories and shit, and they kinda have a chronological order but it's that kind of thing where from one game to another many years have passed or it happens in a different location so... nah, while there IS a chronology to those, they could be enjoyed stand-alone too without MUCH issue
for example these three girls come from the same game, natsu kagura, which is an SRPG who has an old version and a remake version. I just played the OG one recently, and I loved the shit out of it, would recommend, although gotta confess it's a bit lacking in the H department, but it was a very cute story and you really get to see the girls personalities shine.
