No, he's not trying to drop your confidence. He's just saying that you have high expectations because of all your bragging. I mean look at the rest of us, how close is anyone watching us for this contest? Me, I could make a crappy game, and no one would care. Personally, I wouldn't care if you made a crappy one, but others are watching you because you brag so much.
And using characters from the RP thread isn't going to make the game crappy, if I understand your argument, CW7. In fact, with a bit of polishing, the story would be interesting. I just need to clean up Aveyar's character ark, add some more coherence to the plot, foreshadow some things, change a few things around, and it'll be a great game story. Once I do that, all that's left is to execute it, and hopefully make a good short game. I can't wait to try it!
