Everything IS digital! Look at all the APPS available! lol.
We’ve used the method of writing things down as well … but after a few drinks and with a lot of tomfoolery that does get pretty muddled sometimes. ;) This page is just handy for those who don’t want to write anything down or move physical counters around (and risk knocking them … i know that’s happened MANY times with our group)!
No paper money … we don’t use paper money either. We use custom poker chips! :P They’re great! You can play with them like you’re playing poker (they make a wonderfully satisfying noise as you shuffle the stack in your hand) and we usually place the purchased units on top of the appropriate # of IPC chips to make sure we’re not over or underspending.
