Very probably. I don't currently play Pinball Arcade on PC. I bought it on Xbox 360, then again an Android, so don't currently have plans to repurchase them all againThanks Paul G. I see you all have some pretty monster scores there!!!
This spreadsheet is good but it must take a lot for Paul D to update all of the scores. I was thinking of perhaps doing a thread where people post their steam names and then leaderboards would be created automatically on the friends tab. It would just be a case of everyone accepting the friend requests. It's not perfect but could be interesting. Do you think it's worth doing?
But yep, if friend tracking works on Steam (it doesn't currently on the mobile platforms) then go for it.
The spreadsheet is a free-for-all, so anyone should be able to edit their own scores into it if you want to do it that way.
