If you want to start an MMO Rauno, go for one that is newish. Hopping into an MMO full of pre-set community rules/standards with years behind it will simply make you feel out of place and it will be more difficult for you to fit in at the end-game, not to mention if it's something like WoW, you have many expansions to buy.
My suggestion? Play some free MMORPG's (there are quite a few really good ones out there I can list for you if needed), until something like Guild Wars 2 comes out, which is looking to be an impressive MMO and will be new, so everyone (and you) start on the same knowledge level and ability.
