When I left my comment, I was a little long winded...
" City of Heroes should be here. As an MMORPG, this game pioneered many new ideas you still don't see with even new games.
A massive Costume Creator matched by no one, you truly could create you own character not just in powersets, but appearance.
So many power combinations that a single account with paid VIP subscription could not hold every possibility, and new powersets were being introduced every few months.
Architect Entertainment allowed you to create your own mission content.
The Super Group Base allowed you to completely create a space for not just your characters, but those in your supergroup. The customization level of this was on par with maybe Minecraft and above The Sims franchise.
Teaming: As a player you could solo, or team with as many as 8 for mission or AE content. With a league you could push the boundries further by Teaming Teams. I was on one League with 32. What's more, the Super Sidekick system allowed the whole group to be at the level of the mission holder (if too far below, they'd be one level lower) which helped friends with new alts still team with each other no matter what character was being played.
The game was still viable after 8 years with a playerbase around 100k. Number of unique characters created... 43 million... and that was not the cap possible with the customization allowed.
There was so much more to CoH, and I am sad that NCSoft shut down this work of love and disbanded one of the best group of developers in the business. We still hope for a hero to swoop in and save the day, but though the lights have been turned off, our community is still strong and our voices raised high in tribute to this great game.
