Mine was 2009-2010
I really seperated myself from that noobish mentality; pulled away from my characters and focused more on the story aspect
This is easy, 2008-2010 were my favorites
2008: I actually started RPGing at Comicvine, no one really taught me anything I got thrown in shark infested waters with only the rule book as a flotation device.I grew from that had my share of fun.
2009: I fully migrated over here to start my own legacy, Made Gekido that year, and AnimeVice was starting to pick up steam.
2010: This place was awesome full of so much activity. Had 3 teams Battles and stories were happening all the time.
All seriousness though, I think this is my favourite year for RPing. It took a lot of effort to get started, but I guess that made me more attached. Plus, last time I was RPing here, Even my main character was just an attempt to promote Taylor for a while, so it felt more like work, trying to keep up the dark emo past.
This year? Fun fun fun around.
