The superhero genre is a thing unto itself.
And not what we were talking about. Why bring it up?
D&D isn't inspired by RL or comic-book takes on heroism, but by the broader fantasy genre - which includes plenty of action and heroism.
This is sort of a false attack on the DMPC, since all characters are typically mary-sues.
Not so much, no, because players are limited in their excesses by both needing to follow the rules, and by the judgment of the DM. While the DM, ultimately, isn't even restrained by the rules (and in games like 5e is particularly encouraged not to be so).
The idea that bad gaming is always worse than no gaming is completely untrue since it's not a black-and-white experience.
Very true. The answer to 'why should I struggle to adapt D&D to the 'style' I want?' is often 'because it's the only game in town.' There are tons of other games in RPG history, some of them even still in print, but none are as easy to find a chance to play(or run) as D&D, particularly the current edition of D&D.
A DMPC can be just fine as long as they stick to the rules.
Which is a particular issue when the rules frequently punt to the DM for a ruling.
Not saying that a player frustrated with 5e's default feel couldn't get some of the experience they were looking for by DMing, and running a DMPC, just that it's very easy for that to go very badly wrong.
If you're concerned about "rulings" then just don't do a lot of things that require new rulings. It's not hard to do.
Every check in essence calls for a ruling. That's an intentional design feature that encourages players to be accepting of rulings - a cornerstone of 5e's DM Empowerment. You can't, and shouldn't, try to evade such responsibility as a DM, but you should rule for the good of the campaign (the story, the players' enjoyment, &c), and running a DMPC can introduce quite a temptation to do otherwise. Especially if you're running primarily to get a play experience that requires extensive use of modules & house-ruling...
Sorry this is really just a pet peeve for me because I often DMPC and I make a concerted effort to behave. DMing seems to be the only way I get to ensure the quality of the games I'm in and NO, DMing is not a substitute for playing, it DOESNT satisfy the desire to play and it's fun and rewarding in a completely DIFFERENT way.
DMing is not playing. It never will be. One is not a replacement for the other.
They are quite different, certainly, but they are still both RPing, and they are still both fun. DMing is more of a commitment, more work, and more of a responsibility to your fellow players, but it's that much more rewarding, IMHO, even if sometimes, paradoxically, seemingly thankless....
I more or less agree with you in terms of being robust, but it's not the only consideration. When I say base I mean the core of a game in a general sense where if you're customizing its what you build your game on top of and don't really change.
Ah, yeah. There's nothing off limits in 5e. You could change anything/everything. Just last Sunday, I was in a game (my third time as a player in 5e, and the most enjoyable, BTW), where the DM gave us pregens that had stats on a 1-7 scale (just add your stat to the roll), and no classes, backgrounds, feats or racial abilities (most were human but there was an android and a, I guess spirit, as well), just skills, attacks, and a short list of special abilities unique to each. Very cool, but barely recognizable.
Those are good rules, too bad 1,2 and 3, is more or less the kind of things I like to do. I prefer to be a sidekick so 4 is no issue, but most of the time I find combat the least interesting part of the game. Thanks for proposing this, I find this a more likely solution than everything else before.
A DMPC in a support/side-kick/exposition or similar secondary-character role could be more workable than most. If you like being the less-plot-central, side-kick (which can be hard to do in most RPGs, because of scrabbling for spotlight time, needing to make a 'balanced' contribution and so forth), that could be a good way to do it. You'd have to get your RP fix primarily by interacting with the PCs instead of the NPCs. Aside from that, it sounds like a good formula.
It kind of depends on what you enjoy playing. I enjoy playing the brooding antihero, and I found that this sort of character makes for a very unintrusive DMPC. You aren't a big part of decision making because you don't care, and you aren't really social with strangers but can still be someone your friends can count on.
Ooh, another possibility.
