Doesn't have to be NBA 2K13--could be any decent sports game, really. FIFA 13, NHL 13--whatever your poison. Now, don’t just watch someone play the AI (that really is dull). Instead watch a couple of friends play a match. If they’re equally bad, you’re guaranteed some comedy as they fly out from defence and lob wild shots up and down the court (or pitch). If they’re unbalanced, you can expect some spectacular scoring from the better player. And if they’re equally good, then chances are each game will be tight and tense.
Modern sports games offer some incredible animation and presentation too. So while you’re not quite getting the realistic experience, you’re getting damn close to it, and you can create whatever match-ups you like. Late 80s Celtics vs 2013 Heat? Yup. 90s Bulls vs early 2000 Lakers? Yup. Plus, when your friend loses against a clearly inferior team, you get the added bonus of being able to mock them constantly for the next, oooh, year or two.
