Sometimes it's not always easy (or possible) to install your favorite games on your work computer. Sometimes, some Solitaire or maybe a little collaborative Bomberman is as much as you can get away with when you can't install anything downloaded from the Internet. And you'd better make sure whatever you're playing actually looks like work to any nearby screen snoopers around the office.
Throughout a few months ending this past February, Cary Walkin created the perfect solution to this problem: an entire RPG made of a spreadsheet and many macros. The game, called Arena.Xlsm, is a turn-based RPG encompassed entirely in an Excel file. Users can download that and use it to progress through levels, collect items, and battle enemies and bosses with melee and ranged attacks as well as spells.
