DCUO offers a monthly and yearly sub to the game. Every month, every three month, every twelve months.
The membership comes with many benefits, such as;
PC Members also gets "All Access" which share their membership across EQ, EQ2 and PS2 on PC. For PC, it is a subscription and therefore renewing on its own unless cancelled. the multi-month memberships are paid in advance (a FAQ)
With so much things being offered, and to be able to freely progress in the game, membership is required. It benefits the player with more things to do, discover and enjoy. Access to all content, old and new, and the possibilities are endless with powers and weapons choices.
Personally, I do think the membership benefits the players a lot. And with a small fee to support the game as well. As a member, I don't have to buy everything seperately. It's of course an option, but not a must. The monthly daybreak cash\loyalty points are a bonus, that really helps if you want anything off market place. Replay badges are also so important if you want to replay content or unlock a style on your character. and having to keep up with gear (PvP gear and PvE gear) and running a role as well, having more bank slots helps with storing the gear and not having it taking space in your inventory. Overall, I think membership totally worth getting to be able to progress freely. Sub to support the game and start enjoying all content today!
