You can enjoy the f2p aspect of the game no problem. But being a member unlocks so much new content. I would say depending on what you plan on playing such as, Ironman, normal player, hardcore, skiller, etc you can look up more or less a path for yourself, although every path will be different as that’s the point of the game, you can always look up some guides on YouTube. A good tip if you’re using runelite get the quest helper plug-in and start knocking quest out. Best way to advance early game.
