Nice thread!
These are some of the people who made an impact on my RO experience; both the social and combat aspects. I'm only mentioning some of the people I met in my first year of RO, or this post will turn into a book.
Twiztid/Sicker (Ra) - Didn't actually meet him in RO, he got me into this game. Gave me heaps of advice about the game and recommended that I be an Alsius hunter in RA. I ignored him and became a Syrtis barbarian in Horus, but I still appreciate his help.
Wood - Friendly Syrtis conjurer who got me into his clan, where I met a lot of nice and helpful players, and he grinded with me all the way to L50. If not for him and the clan, I would've given up.
Serjio/Suok - L35ish Syrtis marks I used to hunt with all the time, as my PC was shit so I couldn't do fort wars. I would have been very bored of RO if not for him. He also moved to Alsius with me (we were both hunters) and was one of the few hunt partners I'd have.
Ice Cube and No To Studies - Two great friends and hunt partners. Playing besides a warju/healer/tank and that suicidal barb was the best fun.
Rios - He's always had the ability to make me amused or extremely annoyed, in all three of the realms, whether it be in the chat tab or in combat. He's a stupid, arrogant, overconfident, annoying troll, and I've never met a player I like more.
Aarisewan/Aasiora - When I met him, he was a friendly, L45ish player who recruited me to The White Company Dragoons. I remember thinking "lol this pt will never reach 50 or be any good". Shows how much I know. He really earned my respect in the time I knew him, and I don't think I ever told him what a good player and good person I thought he was. ...That sounds lame, I hope he doesn't read this.
Some other mentions:
Lumi, Solomon Dean, Vultureman - Thank you for every LOL your words and actions gave me. It made Alsius a truly unique realm. People should strive to be as awesome as you three.
Lil Hathy - Why couldn't you let players grind at Trelleborg beach peacefully? Why did you have to make life so difficult? Why would you go all the way back there after you were killed numerous times? Thanks a fuckload for making the grind from 35-40 longer and harder than 45-50
Yasur - If not for you, I wouldn't have an Ignis character above L10. You were, without a doubt, the coolest noob in Horus.
