Are MMO's a thing at my age?

A few Neverwinter Nights links

Here're a few usefull links and informations, that'll hopefully help you in NWO:
https://www.reddit.com/r/Neverwinter/wiki/leveling
how to unlock chat, auction house and more.
http://neverwinter.gamepedia.com/Sword_Coast_Chronicles_Campaign
gives you something to follow, and a few good rewards on your way to level 70.
http://forum.arcgames.com/neverwinter/categories/guild-recruitment-pc
look for a decent guild and join one, this will also make NWO easier and more fun to play.
http://neverwinter.gamepedia.com/Astral_Diamond
read up about AD, and start doing those random daily dungeons/skirmishes to earn it.
https://neverwinter.gamepedia.com/VIP_Program
is another good source for a steady AD income from opening lockboxes with the daily key you get from it, and the ViP perks you unlock in time aren't that bad either.
https://neverwinter.gamepedia.com/Leadership
it will take time to rank up this profession, but do it on each character you have, and it will provide you with usefull items (Refinement Points), some Gold and XP in return.
https://neverwinter.gamepedia.com/Invocation
another source of useful items and bonus XP.
https://neverwinter.gamepedia.com/Events
can give you a whole boatload of free items and AD. next one in line is the Winter Festival, get one character to level 30 before it is active, and you can make millions of AD from it with a bit of loot luck.

hopefully more free ZEN, when it's up and running again.
And when you want to spend ZEN, be smart and only "shop", when they've a winter/summer sale (40% discount on anything) going.
https://www.reddit.com/r/Neverwinter/wiki/currencies
last but not least, read this before buying ZEN through Steam...
