I learned rendezvous from CoD. I learned so much from Pokemon. I started when I was about 5 or 6 and learned things like status, paralyse, accuracy etc and learned things like immunity and phoenix from final fantasy, which in turn lead me to learning bucket-loads about Norse mythology and how Fenrir was one of the sons of Loki and Odin was the god of poetry and war and literature and stuff and he had an 8 legged horse called Sleipnir and in the end there will be a big fight called Ragnarok which will flood the world and Fenrir will kill Odin but Thor and his hammer, Mjolnir (learned that from Halo) will survive and some others.
Synthesis, learned that from Kingdom Hearts.
Runescape taught me how metals were made by mining ores from rocks and smelting them together in furnaces to create liquid metals which had to be poured into molds.
Also learned what fletching was and why arrows have feathers on them from Runescape.
Oblivion taught me things like sanguine, which lead me to get extra marks in Spanish classes when I realised sanguine is taken from a Latin term and i=I was the only one who know what "sangre" meant.
It also taught me of the mortar & pestle and words like endurance.
Other rpgs taught me about wisdom, intelligence and constitution and playing online perfected my spelling and typing speed.
Also, lots of names of characters/locations in games are based off latin/greek words or famous people or things like sanguine, or the xenoforms from Alien vs. Predator which lead to me learning that xenos is greek for stranger and xenophobia is a fear of strangers/unfamiliar things (also foreigners.)
I learned musical terms like Bolero, Serenade (from Ocarina of Time), Rhapsody and Elegy from Kingdom Hearts.
Listening to VG music taught me about harpsichords and cellos and viola, violins etc before we were taught them in music classes.
