When I started WoW 3 years ago, I continued playing for 2 years. From the outset, I wanted to raid with my friends.
Instead, I spent exactly 1 year hitting level 70, at which point all my friends left the game until Wrath of the Lich King came out. Then I played until Lich King arrived, leveled to 78, then got laid off and ran out of money for monthly fees.
I enjoyed the game, and I had 3 or 4 friends that I played with regularly. We had fun...but if what I really wanted to do was raid the whole time...why 70 or 80 levels just to do that?
I propose an MMO be created, designed for raiding from the outset of the game. If the whole game were based around a series of raids, some of which were accessible from the very beginning...would it really be a problem? I think if the game developers designed raids for beginners that didn't really require a lot of communication, then built up to more and more organization as you went, certain players would find it to be a good experience.
This wouldn't be for everybody, but most especially for the people who started an MMO with the intent of "getting to 80 so I can raid with my friends."
How would you design an MMO around raiding? What challenges would you foresee, and how would you deal with them?
