I kinda agree with you AND with that post you're talking about. Dealing with OCs is like being both a parent and a god to them. You want the best for them and you'd like to do only good for them like a parent, but you also need to keep the world interesting and balanced, like a god. I guess the most important thing is the equilibrium, and deciding of how much of a parent and how much of a god you are in each case.
Warnings are a fair thing. I'm really into gore so only very few things would scare me off, but some people are sensitive. The main game I'm working on will have some very graphic bad ends, so yeah, I'll have to put a fair share of warnings too. Though I've decided to take my time with that game and release a simpler and shorter one first, that would royalty free music, no voice acting and things like that. Cheap to make, cheap for the players, and I'll get at least some money for my main project. Well, I guess this one will have some bloody moments too as it's about knights, but oh well XD
