Why would this be beneficial? What, in your opinion, would make this an attractive option for players to enjoy?....There is a challenge here, of course, and I expect players who "only want to play what I want to play" will say "no". I also understand for many people playing time is limited, so having that view is not by default a bad one (no judgement here!).
As I opened with, I have run such games in AD&D with a lot of success, but with modern views I am not certain how well received it would be.
Yea, there's a lot to be said for procedural generation of characters. Two of my favorite old-school games (Beyond the Wall and WWN) both heavily feature this, and I really enjoy the rules around creating the character.But for anything longer I guess I prefer a bit more of a hands-on approach, even if all those hands are doing is rolling a lot of dice and writing down the results. I've done the completely-random character thing numerous times in long-standing campaigns and some of them have worked out quite well, so if a whole campaign were slated to start out this way I'd be in like Flynn.
This is my answer too. Some GMs I will do whatever they want to run because I trust it will be fun. Other GMs, not so much.There are some DMs I’d play that game with, sure.
If your goal is to get players to try something unusual, I think you'd get better results (if your players know each other) by having them build PCs for each other rather than assemble them randomly.
I think the first question here is to the DM. Why?So, the question: would you play in such a campaign?
The bolded is, I think, the whole point: the idea is that instead of going into char-gen with a character concept already built in your head, you go in with a blank slate and then adapt to whatever the envelope (or dice-rolling) gives you.The change is a pretty major constraint on playing the class/race/archetype that I would like so before committing myself, I would want to know why the DM thinks this would improve the gaming experience.
In my most recent game group, this would be akin to torture for a couple of them.Or, how about just tell them, "Folks, for this game, I'd like to see each of you play a race & a class you haven't played before."
Speaking for myself only, I wouldn’t say this is a minimal impact thing for the GM.“To try something different” is also a response to be wary of. I am always wary when “try something different” means “different is a large impact on you, minimal impact on me”.
