I used to use one of these old serial Microsoft trackballs for a few years. They use less desk space and they were much more reliable than contemporary ball mice.
I think the high quality of even cheap optical mice has made them obsolete. Their high precision means that they also don’t need a lot of desk space and they are more reliable than trackballs.
I think the main reason to use one of them today is probably nostalgia and personal preference.
















I think it’s totally valid to run a realistic game where realism takes precedence over game rules, but then the “passing of the object” part fails.
It’s also totally valid to run RAW game, but then it fails like you said.
So no matter what game you run, the railgun makes no sense.
What would make sense with a RAW game is to use the railgun for fast travel/fast transport, but then again for it to give a decent advantage, you need thousands or millions of peasants who willingly cooperate, which also won’t really work in most games.
