Ask HN: Satoshi Was a Gamer?

Many people have written about Satoshi Nakamoto's expressions and words, like

"bloody hard" "order of magnitude" "hosed" "fencible" and "Nakamoto" (the Japanese name itself),

but few have discussed these words from his 2009 emails, https://mmalmi.github.io/satoshi :

"pwn" "retarded"

So in addition to Satoshi obviously being a programmer, was he a gamer?
