So if you absolutely can't do something IC unless you've done it OOC how exactly does the inverse work? Do we all have a right to claim we personally killed Gaius just because we all did it in game? I don't think people should be restricted and penalized for something as understandable as not playing the flop that was 1.0.
Well, again that all comes down to who you will take you seriously, which is what the thread is about. If someone said IC that they personally killed Gaius, I'm sure everyone here would have their own thoughts, and IC reactions. I've always thought that such statements that boast your character as the one who shapes the world for us all to be ridiculous.
There's nothing wrong with catching up your story if you didn't play 1.0. Ultimately it's up to the people you're RPing with to believe it or not. So if someone plans on being the best, or writing that their character ended an era, they better have done their homework. As I'm sure more traversed players will be willing and able to poke holes in their limited knowledge.
