Disability representation in tabletop roleplaying games is one of those areas where you might not expect competing access needs to crop up, but there’s a subtlety to it that a lot of folks overlook.
On the one hand, it’s absolutely reasonable to expect this type of representation to be reflected in the game’s mechanics as well as its worldbuilding, particularly in systems where the rules are fine-grained enough that you’d intuitively expect the particulars of what you can do and how to be mechanically significant.
On the other hand, there are levels of mechanical engagement to consider. In brief, some games give players many discrete “rules toys” they’re expected to engage with in order to effectively play the game, while others provide few. Even within a single game, how much rules engagement is expected may vary from character to character; this is particularly the case in class-based RPGs like Dungeons & Dragons, where one player may be wrangling a list of spells as long as their arm, while another player’s only mechanically significant decision from turn to turn is which monster to hit with their sword.
The critical insight is that supporting varying levels of mechanical engagement at the same table is a feature, not a bug. Some players prefer to have many rules toys to play with, and some players prefer to have few. It’s a good thing when a system can accommodate both of these players without giving either one the shaft in terms of spotlight time or ability to make mechanically significant contributions.
Now, here’s the kicker. When you’re implementing your rules for disabled characters, you’ve gotta ask yourself: am I creating a situation where disabled characters are categorically more complicated to play?
And if I am, is this warranted?
This is not, of course, to say that having crunchy rules for representing disabled characters is never a good idea. You’ve just gotta be mindful of how you go about doing it, and what the results of your approach are going to look like when the dice hit the table. Somewhere out there, there’s a disabled player who’d love to see themselves represented in the rules, but who also really just wants to hit things with their sword!
