Ass 77 mentions, their is a ton more implied by creature size than just the number of spaces they take up. What all benefits and disadvantages are you also considering for size adjustments? Are you looking at some from 3E stuff like to hit and AC modification? Carrying capacity? weapon damage?
Personally, I'm very weary of size adjustments, didn't like most of them in other editions, don't like the idea of them in 5E.
I know Large size characters are a taboo in D&D. But now in 5e, I just dont see any problem.
Moreover, Large characters are important in fantasy, playing the Big Guy (one-man army) archetype. This needs to be possible. (I find the excessive abundance of Small player characters at the opposite side of the bell curve, to be somewhat annoying.) Linking size to Constitution hopefully creates an elegant universal mechanic to explain and build a Large size character. In the Monster Manual creature size strongly correlates to the Constitution, and the few exceptions are close enough I dont need to worry about them. Already in official stats, Constitution ≈ size.
Large is not so large. It is someone roughly between 8 feet tall and 16 feet tall. A character who is 10 feet tall, for example, will be conspicuously ‘big’ for thematic flavor and narrative implications, but will be able to at least ‘squeeze’ thru most locations.
My main objective is simply to assign the ‘L’ onto a character whose player wants it. But I also want it to be part of a normal gaming mechanic, that applies in all cases. If it is ‘normal’ according to the rules for a Large character to wield Large weapons, then I want to take this into account. The Constitution≈size is to be an adjudication tool.
So for example, if necessary to quantify the stats of a young Human child, the small size correlates with the fragility, and so I can easily eyeball the Constitution score as somewhere between 5 and 8, depending on the child.
Just let them be large without any additional cost. It works just fine. I have typically found most players start to dislike being large once they find out they can't go into 75% of dungeons, and 95% of places inside of a dungeon. Or buildings. Or that really tight crevice that is the only exit from the cave. Or ya know, being an obvious monster race.
Taurs ignore the weapon size issue, so there's less mechanical trouble being a Centuar or a Drider than say, being a large minotaur, loxodon(ravnica elephant people) but realistically outside of the most accepting and metropolitan settings these races all have trouble operating in normal society. Crafted items cost substantially more, getting ahold of weapons sized for you is very difficult.
For murderhobos? Large races are HIGHLY abusable. But I mean, you know if you've got murderhobos or not.
I've allowed large races in 3E, 4E, and 5E. Just by saying "ok you're large now".
For 5E: Yes, they take up more spaces which allows them to control more area, but this issue is resolved with existing OA limitations. Yes they have larger weapons which allows to deal more damage, but it's not any more than a well-built barbarian (assuming they're that, it's like 3-4 points per hit). Yes they can carry more weight, but IME being the party mule is rarely their desire.
End of the day advice: just be prepared to present them with situations where "being big" is a drawback.
I agree with the sentiments here. Just say, ok now your Large. My main objective is the thematics of character concept. Yet, mechanically, body space applies. Also weapon damage, so I want to mitigate these mechanical implications.
I liked your point about how 5e limits the benefit of Opportunity Attacks. This is probably why Large seems no big deal in 5e.
