If you need to generate some basic cards for your games, you can try this web-based utility, which imports information in CSV files. Put your data into a spreadsheet, save as Comma Separated Values and upload. Voila!
Cardmaker is a tool for using CSV files to easily generate cards for your games.
Lately, I’ve taken to making cards for units in my games, rather than putting it on on sheets of paper. Having the cards cuts down on table clutter and makes it easier for players to find exactly which unit info they need.
