<p>Read the VN, Stay Night before all else. After that you can read the Fate Zero light novels which serve as a prequal to it and Fate Hollow Artaxia which serves as a sequal. As for the other novel series you can probably read them in any order. </p><p>For games it would be Extra, than CCC, than Extella. The problem is that Extra has some very boring gameplay so it's probably better watching a playthrough. CCC also has never been localized so the best you could do is read a translation of one of the routes. Extella is fine to play tho. </p><p>As for the anime it would be Zero, than UBW, than the releasing Apocrypha. You could also watch the original DEEN anime of Stay Night but it's a little on quality since it was made so long ago. The kalied anime and manga is also an option but that depends on your tastes. </p><p>Also you can also play the app game Fate/Grand Order which is basically the newest entry in the series and is really introducing all the newcomers into Fate, be warned though that it is a Gacha game so take that as you will. </p><p>Any other questions you can ask or find in this wiki or you could go to one of the Type Moon centered forums like Beast Lair to interact with other fans. </p><p>This is all my thoughts on this anyhow. </p>
