At this point I don't think it'll be very productive to continue arguing with
@71342 directly. If anyone else has similar concerns as him, but is willing to give my game and characters a chance, feel free to voice those concerns again, and I'll address them to the best of my ability.
One concern that several other people seem to have is that they think my character is simply too powerful in comparison to the rest of the setting. This is not true. The reason that the sorcerer-king decided to merge with the Dweomerheart and become a god, even though he could already destroy mountains before that, was that he knew he wasn't powerful enough to conquer the world unless he gained the extra power from deification. Without the power level of a deity, he might've been able to take out any other mage in the world at the time in a one-on-one fair fight, but he'd have absolutely no chance if they all attacked him at once, unless he became a god. And now, he's quite a bit weaker than his pre-deification self. There should exist quite a few characters, on both the Magi and Tech sides, whose powers are on the same level as him, and most of them should have far more political influence than my character due to likely being leaders of major factions instead of a nameless recluse. It is simply not true that my character could easily solve all of the world's problems with a snap of his fingers if he wanted; he isn't nearly powerful enough for that. If you want to play as one of those characters whose power level is comparable to my character's, you can discuss your ideas with me, and we'll see if we can work something out.
Secondly, as
@lydyn already pointed out, there's no essential difference between a "PC" and an "NPC", especially since everyone is allowed to make as many characters as he or she wants. All characters are just characters, whose actions are, one way or another, decided by the players (counting myself as one of the players), so it's not very meaningful to arbitrarily label some of them as PCs and others as NPCs.
"I don't have to mention any weaknesses,"
This is only because including all of the weaknesses and limitations will make the character sheet even longer. If you want to know the limitations of any particular ability of my character's, ask and I shall answer. I have a set of very strict rules in place in my setting, and no one, not even my own characters, can break these.
"my characters can be defeated, but only when I decide they can."
I'm the GM. It is always the case that my characters can only be defeated when I decide they can, regardless of how powerful they are. I've made my character powerful not to make him invincible (there exist other characters who are each nearly as powerful as him, as I said above), but because I want to explore the idea of how it's not easy to change the world for the better even if one has a lot of power at his or her disposal. Also because of personal wish fulfillment, but again, I don't think that's a bad thing if the character itself is compelling and well-written.
If theses are DMPCs as opposed to NPCs, they will have to take a serious backseat to the players; essentially demoting them to NPCs regardless.
See above for the lack of fundamental distinction between PCs and NPCs. If your concern is one of plot importance, I've already said that I will do everything in my power to make sure my characters do not ruin the conflict for the other characters. One of the symptoms of a Mary Sue is how she can warp the plot to revolve entirely around her, and that is something I specifically want to avoid. I will not turn the plot into "Evan's quest to revolutionize the world, with the player characters as his lackeys". What I intend to do with my character is to explore his personality, motivations, and psychological issues. It's a psychological journey that's intended to end with him becoming more at ease with himself, not a physical journey that ends with him having changed the world to suit his views better. The other player characters may play a part in his psychological development by interacting with him, but they're certainly not going to become extras as he takes center stage and decide the fate of the world.
I find the CS with ots extensive list of the character's many powers and whatnot to be rather masturbatory.
Yes, it's indeed masturbatory, because it's wish fulfillment. But, as I've said a few times now, I'm also trying to make a well-written character out of this. Characters should be judged on their displayed quality alone, as if the author doesn't exist. Because as far as the story itself is concerned, out-of-story elements like the author really don't exist.
I've got my reservations about the character, too. There's not enough buffer between you and being absurdly overpowered because you... Sort of removed them all, for yourself, so we just have to trust you. I don't know you, GM--I can't do that yet. Only thing I can trust is the setting you laid out, which has a lot of writing and research gone into it.
Currently, I'm giving you benefit of the doubt, but if it starts turning fishy in here, I'm out.
And this is perfectly reasonable. I'm new here, and you guys haven't seen me roleplay or host. But as long as you give me a chance, like what you're doing now, my actions should speak for themselves when you witness them.
Oh, about the half-elemental thing. If anyone is interested, I'm fully willing to explain why my character is technically classified as a half-elemental, half-dragon, and why such a thing isn't all that abnormal, relative to everything else in the setting. But I don't want to bore people with only tangentially related minutiae on how speciation (or the lack thereof) works in my setting, so I'll only go into details if anyone is actually interested in the worldbuilding.
