2-3 years, huh, Question? I didn't realize you were here for that long.
Well, about me, I've been here for years...5-6 years, one would think, and I remember that the first RP I joined was called D-Day Invasion. It was a single line RP and it was pretty fun and fast paced with some wacky attacks and counter-attacks. The first RP I created was called Paintball Wars, which was also a single line RP. The funny thing about this RP was that I had no experience with paintball.
I remember actually borrowing a bit from the initial post in D-Day about playing cards in the middle of a battlefield and applying it to my RP for my starting post. It became quite successful (something I had never even thought about).
Around that time, I ended up reading some of borg's stories. Now, I had written some stories in the past, but they were short and I never finished any single one of them. However, the way borg wrote, the way he made it so interesting, made my mind go kinda crazy with imagination. Soon, I started writing out "The Two Stars" and it not only gained a number of readers, but even caught borg's attention. He even asked me to join in a collaboration with him and three other writers, which would've become the ultimate Roleplay Forum project if it had finished: Experiment 148. I would write a sequel to "The Two Stars" called "Fraudatio", which disappointed some people by the ending.
I've created many roleplays and joined numerous others, but perhaps the one roleplay that really made things interesting was the famed Mobile Suit Wars by JackShadow. It is the perfect example of a one-liner roleplay turning into the story-driven, multi-paragraph universe that ended up becoming the end of the series. It was chaotic, it was fast-paced, and it was an ever-changing roleplay with something new happening. We always joked that not a single character would die in the roleplay because we'd come up with some imaginative way of them coming back (Blonde's character becoming a cyborg after death, Silent's ability to somehow cheat death, and others). It was fun.
I've run out of time, so maybe I'll post more later. Tata!
