I see a few potential paths coming out of this, assuming it goes through. (Which would be nice.)
1. The game is restored to what it was at shutdown and existing accounts are preserved through some means. (I've got mine saved as Sentinel files!) This is, of course, the ideal. We'd all love to be able to pick up where we left off; I know I had literally dozens of characters that I wanted to level up, from Queen of the May (Nature/Water Defender) to Worst Ninja Ever (Ninja/Sonic Mastermind). This is the dream scenario, and I'd be surprised if anyone disagreed.
2. The game is restored, but NCSoft does not part with the customer data or does not have it stored. I'm okay with this. I mean, it's not as good as option one, obviously. My account dated back almost to launch, and I had all the powersets and all the shinies and over twenty Level 50 characters and Incarnate goodies. But I loved playing the game, and the chance to play it again would be enough for me. Everything I lost, I can earn back by spending time playing the game...and you know what? That's kind of something I wanted to do anyway.
Day One would be a Street Fighting/Willpower Brute. Because SMASHY SMASHY SMASHY!
3. NCSoft sells the IP only, and the buyers make a new game with it. This is the diciest of the three propositions; I stayed with CoH when DCUO and CO launched because I liked the gameplay of CoH better than the other two games. I liked the team structure, I liked the customization options, I liked the control setup...basically, I'm really used to CoH, and anything else I play to fill that gap would have to play like CoH (or improve on its experience. I'm not saying it was flawless or anything.) I'd be willing to give "City of Heroes 2" a try, just like I'm willing to give all the successor games a try. But it doesn't earn my automatic allegiance.
