You should make a multiplayer version where both players have blacksmith shops across each other and can steal or nicely borrow each others money or iron or swords. just a friendly blacksmith vs black smith. Max shop should be 1-4 with 4 players max for working together in one shop or 3 in 1 shop and 1 in the other and vise versa. so a fun roleplay / trickery game. Or even a race or time based battle to see who can have the most money or can get to a certain amount first.
