New player, never touched this game

Hi guys. Im a HUGE fan of mmorps, and recently i decided to play the classics that i never tryed, like eq, ultima and osrs. How f2p the game really is on standart servers? what can i expect of the game? the people are friendly to newbies? i just wanna have fun, but if i like, may i continue playing for a longer time. In this case, how much grinding has to get just a little strong? thanks
