Awh, this thread brings a tear to my eye. I had a thread on the same topic in the official RSC forums before they were removed recently..
I have so many, it's hard to say which is my favourite. But I suppose I have two favourites that I can think of quickly off the top of my head.
My first favourite was probably when I finally saved up enough gp/other rares/certs to be able to finally afford my beloved pink partyhat. It took quite a while to get and I was so nervous the deal wouldn't go through after quite a lot of negotiation, but it did, and I just remember feeling so relieved and happy that I finally did it.
My second favourite memory is PKing with a small group of clanmates during one of the re-openings when RSC and PKing was temporarily revived. My RSC account was always built for PKing (though I never got to reach my perfect stats, I was somewhat close), but only rarely did I get to PK in recent years. So any time that I was able to, especially with friends/clanmates was always a cherished memory. I remember many a night staying up late patrolling Wildy and BS'ing with the clannies. I miss those nights, and those people.
I also really enjoyed group questing and helping others do quests by being a blocker for them, carrying items for those doing Legends, or just being a guide. I'm actually rather glad to be able to re-do the quests here in RSCR. It's been so long since I did them myself.
I'll leave it at that, since I could go on and on all night if you let me. Thank you for creating this thread. It makes me happy to be able to read through all the fond memories.
Sometimes you will never know the true value of a moment until it becomes a memory.
RSC - gone, but never forgotten.
