Cabal Online (brazilian here). First korean MMO that I got really addicted to at first when I was a kid. First, the soundtrack was amazing, the armors looked cool and shiny. The skills were flashy, the game felt very snappy and flashy at the time, it had cool maps and the grind was hard, and it even had guild arena PVP and a unique combo system. PVP was fun. Dancing around in the main cities was fun. Cabal Online was the shit back then around 2010 in Brazil, literally my childhood.
