Pretty much any Lego game is worth trying out if you’re interested in the franchise. But for sheer breadth of content, you can’t get any better than Lego Star Wars: The Complete Saga. This isn’t the new Lego Star Wars, though; it’s the 2009 Complete Saga, which means Episodes 1-6.
Aside from meaning you’ve got six Lego games to play through in one package and more playable characters than you can shake a lightsaber at, it also means basically any computer can play it. There’s co-op play involved as well if more than one person wants to join in the fun. With character customization, hidden bonuses, and challenge modes, busy you and your younglings will be for a long time.
