As someone who teaches people how to play L5R (i'm pretty useless in tournaments, as i tell my opponent how to beat me)
Picking up Netrunner was a challenge.
Saying that though as it's similar to L5R where you target a location with an attack, it's more about Strategy and knowing when/where to use limited resources. which is easier to pick up from a L5R background.
in Learning Netrunner, the entire group i play with are L5R players, and with that we use comparison of that games many strategies to get around the Lingo.
Where we play there's a coupld of the magic players that ask about both games, With that i'm always up for teaching.
The Simple way i've explained how to run Corp to a magic player, is you treat each Server as an individual game of Magic, you defend it as it was your entire field. The standard reply to this is "when do i attack?" in which i reply. "in your defence"
The opposite side of this tail is for the Hacker. "Go for the jugular" "See a weakness go for it" and "Don't hold back"
in a Show game between a friend, I unfortunately finished the game in 5 minutes with stupid attacks. As it was a demo, the magic player was happy that the games do have a difficulty curb (i was playing a unedited Shaper Deck against a Weyland Custom. As it was a Demo, we explained how the cards worked and how you had to attack to the weakness.
As a CCG instructor for L5R, i'm still learning all the differences with Netrunner, but it's a Fun challenge. Never will i call it hard.
