PopCap Hits! Vol 1 achieves everything that PopCap out to do with the likes of Bejeweled 2 and Astro Pop. They're very addictive games, yet their underlying concepts are so simple.
PopCap Hits! Volume 1 is a great compilation of games for casual gamers who love puzzle titles. The conversion of both titles is good, and the saving system, especially for AstroPop, is more forgiving for gamers who found these titles a little more daunting that usual.
Yes, Bejeweled 2 and AstroPop are fun titles, but they're free on the Internet and don't justify a price tag of $20. Even if you were aching to play these games and had no access to the World Wide Web, I'd advise you to hold off and wait for PopCap to hit the bargain bin.
