Grandize puts you in charge of a brand against two rivals, with $5,000 in cash. Twenty periods, under an hour. Here's how it works. Leave the seed blank for a new market, or type the one your professor gave you, so the whole class plays the same game. Three companies. The columns that matter are price, quality and awareness. Each rival is labelled with its strategy: one discounter, one quality focused. Everyone starts level. Each period you set a price and decide how much to spend on quality and advertising. Spending can't exceed your cash, so every dollar has to earn its place. Change nothing and advance. You banked the most cash, but your customers walked away: a quarter of the market, against 36 and 39 percent for the rivals who spent. Customers weigh price, quality and awareness in proportions this market keeps hidden. Watch which rivals pull ahead: that's your clue to what customers value. Put $1,000 into quality. Your score jumps, your share climbs to 29 percent, and your cash dips. Spending costs now and pays later. You win on company value: cash plus what your customers are worth. Hoard cash and your brand fades. Sell at cost and your customers are worth nothing. The Guide explains every number and maps the game into the marketing mix. Start with level 1. Good luck.
