Totally agreeable, ive played WoW since PRE-TBC for a bit (got to level 21 rogue and skinned in westfall all day lol) then I came back TBC and started a paladin, pretty much played paladin since, both holy & protection, for me personally as I say, it started with daoc, was the best game MMO wise in my opinion, medi-evil graphics and relics/keeps you had to capture aswell as multiple other bits and peices, but I do think WoW was good whilst it contained alot of people, but now we see alot of newer players who don't help others/the economy, and destroy some of the WoW based stuff.
RIFT I have been playing for around a week now, and is amazing, don't get me wrong each game has its flaws, but hey who knows I may try WoW a bit again down the road, afterall ive got 6 nearly 7 90's
I think the fun you have on WoW is based on your realm, I play on The-Maelstrom EU which is a really active PvP realm which always keeps me occupied doing, BG's, Arena etc...
As for RIFT I've only tried a trial, and I thought it was pretty fun, didn't really get into that.
My online gaming started with Runescape when I was really young and my cousin introduced me to it, after a few years on that, I heard a few students in my class mentioning WoW and thought I'd give it a go, and I loved it
I didn't start until Mid Lich-King though.
What do you think is better WOW / EOC RUNESCAPE / OSRS
Going to say WoW for sure, then OSRS, EoC make's me physically sick.
