What was yours?
I think my favorite experience was the first week of the F2P transition, I was running in-game chat competitions to win prizes for the new players, games like "Come find me in Silverwood" where i would give my location and the first 3 players to turn up would get platinum and a pet and some bags. i did this for a solid week, i asked CS for some more items to give away and they donated me around 40 bags. There was this one guy (i can't remember your name, im so sorry) that donated me a LOT of stuff like money, bags crafting mats pets etc to give away. i met loads of great people and had a really fun time on my toon Ordagthin.
I no longer play RIFT, but i was feeling nostalgic.
