As I understand it, APB was essentially an MMO similar to what Brink is now. Cops and robbers. The customization video displayed some remarkable options, though I think that game went the way of Auto Assault.
I could be wrong, and doing a Wiki-search would probably yield more accurate answers.
But I'm totally with you on the whole City of Heroes versus Champions Online thing, Adepta! City of Heroes (until recently) had a terrific aesthetic, and it was more of a post-modern real-world setting which just so happened to have meta-powered humans (and non-humans) running about. Champions is a comic book game. In fact, the original lead developer of City of Heroes abandoned the game in a huff and went on to make Champions for that very difference. City of Heroes was what it was, and it wasn't 'comic booky' enough for ol' Jack (at least as the rumours put it).
I had multiple subscriptions to City of Heroes (or more to the point, City of Villains, while they were still separate), and sunk thousands of dollars in to that game. Until the trifecta of Bad Calls drove me away. Matt Miller making 'end game' content, despite the game's selling point being "it's about the journey, not the destination." I wouldn't have minded so much, either, if they had actually approached the content with their primary consumer base in mind, instead of just mimicking w.o.w.
'Castle' deciding to modify the fundamental function of a power which I personally thought was fantastic, despite officially stating they'd never again break the 'cottage rule' . . . just to kowtow to number-crunching power-gamers.
And, most emotionally brutal of all, 'War Witch' Bianca declaring the game an "online comic book" and nothing more, while past Devs had very carefully avoided using that label in an effort to acknowledge what they actually HAD created, instead of what 'Statesman' Emert had tried to make.
Sure, I'm just ranting due to bitterness. I had spent a long time in that game, and it actually helped me through some personal life issues, actually. I realize it wasn't a game meant just solely for my enjoyment . . . but those three events all happening in a single week, during the Going Rogue beta . . . just totally disenfranchised me. It was the moment I realized the direction of the game's development was opposite to where I would have actually derived enjoyment.
If that upcoming modern-day MMO with Illuminati and Templars and all that offers a level of character customization on par with City of Heroes, then I may be inclined to check it out.
