...I used to roleplay back in the AOL chatrooms too, holy shit. But, I did Turn Based Outpost. Basically the only way to attack or defend against an attack was to post more chat posts than your opponents.
That sounds like simming. I didn't get into the RP thing, but I did "SiM", which was just DBZ chat room combat. Putting your moves into :: :: or -= =-, if your opponent typed something faster as an attack you had to type the attack as if it happened, etc. In essence, it was just one giant typing test.
Example:
::leaping roundhouse kick to the face, sending you flying backwards::
etc. etc.
In the fight you had to type out charging or some shit and not get disrupted, all setting up to using some DBZ finisher to win.
Or the noob version:
::teleport::
::break neck::
I was up to 100 WPM with balls-on accuracy in 7th grade because of this shit. Hell, I knew most of the DBZ names and moves in Japanese because of it as well. Always fond of Piccolo on the show so I rolled with the special beam cannon (makankosappo... had to Google the spelling but damn I was close!).
I can't stress how lame this seems in retrospect. And how awesome.
