@frog *hahem!* Do you know the worldwide aclaimained MMORPG named Final Fantasy XIV?
More seriously, you can play a free trial including the Heavensward, Stormblood and Shadowbringer extensions (so around 200 hours just for the MSQ). You can play all the jobs you want (starting with one, you can unlock the starters jobs as soon as you reach lvl 10. Then you can unlock more advanced jobs at higher levels like Red Mage, Samouraï, Gunbreaker, Astromancian, Machinist, Reaper... You can also get crafters and gatherers jobs ^^
The community is really friendly and helpfull with sprouts.
Did I say that the story is one of the best?
