I agree with Katashi as it's a matter of opinion.
My suggestion? Take a liking to eden if you think you might want to stick with us. Play a while, join a guild see everything the game has to offer and then make a decision. Maybe do the same for the rest of the games.
In my opinion it's totally worth it. Theirs just so much to do in eden between trials, achievements, guild pvp events and theirs only so much more coming later what with all the patches still waiting to come out.
Eden has alot to offer, you should explore that and see if it's to your liking and see what other mmo's Aeria can offer too.
Hope you stay with us o/
