I mean, I can't always dedicate several continuous hours to a game, and my free time is often more conducive to short 10-minute bursts. If you're the same way, then you've probably heard of casual heavyweight PopCap, provider of the many versions of unicorn-festooned, ball-bouncing, peg-popping addictiveness. But perhaps Peggle was a one-off deal that managed to charm its way into the hardcore crowd's awareness despite its sugary coating? I think not, and I have five reasons why you should pay attention to PopCap's next game: Plants vs. Zombies."
