Okay, first of all, "dice" is already plural. Unless you're talking about cooking, there's no such word as "dices".
Like most gamers, I love dice IRL and have far too many. Yet I find myself unable to care about what they look like in a computer game, if they aren't functionally different in some way. But it's likely I'm in a minority here - I think DLCs that just change the look of dice have done okay for other games. This would probably be popular if someone did it, though I'd probably mostly ignore it myself.
OP may not a native speaker.
I also made the same mistake, English is the 4th language I speak so I apologize for the mistake too.
