The big difference is that on Day 2, somebody knows somethin'.
They don't have to reveal it, but even if a cop found another townie on Night 1, it's improving the odds of the town finding scum with "random" lynches.
I don't have any real suspicions against Robert or iSocialism as evidenced by the weak support given.
But we have to start somewhere.
This basically. But if we guess right D1, and hit a scum, or even put pressure on them we maybe get some scum to try to divert the attention to someone else. That's why I am for at least Mod's making D1 purposeful by a needed D1 lynch of at least 1/2, but the person has like 50/50% of actually being killed off. At least there's something to possibly play for D1, otherwise it's not gonna happen. There will never be enough solid proof D1 to warrant a real lynch, at best speculation, and not enough people in pretty much most the games I played that are willing to risk it unless it's forced action. D2, at least roles have some sort of information, be it limited or not.
Like i said, D1 is mostly for people to chat with one another, make witty quotes or something, and to boost their post count up to get out of looking suspicion while not actually contributing anything meaningful. It is a good gauge to make sure everyone is actually playing, if they're not posting at all, but about it.
I'm not necessarily against D1 lynches, but there's no pressure/purpose to play the game or post anything meaningful, so because of that there's no real good info to push a lynch on anyone.
