It is worthy to join RS membership

Free to play is a good thing. You can test the game, look around, see if you do well with the other players and then decide for yourself if you're ready to pay. Nobody's forcing you to pay and as everybody said before, you can do well without paying. Someday you want  more, get your paypal, credit card, paysafecard or whatever you're using and get more quests, better weapons and whatever they offer.
As for me, I got bored somewhere at level 20 and never paid a cent for Runescape.

Membership is deffinelty worth it. You get a MASSIVE and i do mean MASSIVE amount of content for you few dollars...

Few" dollars became 8$ with ages, but content turned to buy to win (SoF) + still weird grind.If you join membership, you can buy cheap rs gold from official site.

f2p is ok if you don't have a good comp and have time to waste...
read game forum too, by the way, time to time you can find like 300 pages of rants there.But you can find easy and fast way to earn rs money.

I found it worthwhile to put in a few $ to get full access to the game.You can get discount to buy runescape gold.. I would definitely recommend the trial version first though and then just go from there... if you like you buy, if you dont you try a different game!

Out of curiosity how do you guys pay for online games and the likes?  I am trying to get rid of CCs and am looking for easy online payment methods? Havent found anything as of yet...
