Wii Brothers, a game manufacturer, has a new idea for an adventure game. It can market the game either as a traditional board game or as an interactive DVD, but not both. Consider the following cash flows of the two mutually exclusive projects for the company. Assume the discount rate is 8 percent.

Year	Board Game			DVD
0	$	1,250		$	2,800
1		700			1,800
2		1,000			1,580
3		220			850
