One time I played in an Adamant game as basically a race of script-kiddies (though I may have used the "magical" paradigm for some odd reason)... I wrote all my messages in l33t, seriously ticking off Fyron both in-game and out, and it was unfortunate that "pirates" hadn't been added to Adamant at the time as they would have fit perfectly with my empire's bent, if you get my drift
In CB-Deluxe #1, I'm playing as the Gorons from the Zelda games, and as everyone knows, Gorons end all their sentences with a mumbled "goro"
In Gritty Galaxy 2, I'm playing as the "Protonic Avengers", led by "Captain Proton" (any resemblances to Lt. Paris' 1950s sci-fi hero on ST: Voyager are entirely coincidental
), and I often end my messages with "To infinity and beyond!"
In P&N Syndicate Wars, I'm the Zebesian Pirates from "Metroid", and as such I like to send messages such as "The Mother Brain has considered your treaty proposal and reluctantly accepts."
