I'm not really into video games. If I do play games, it's usually small and fast games; games you can start up and play for 15 minutes without having to go through a story, or determine long-term strategies. For a while now, I've been playing Bejeweled 2, the extremely addictive jewel popping game from PopCap Games. I think this market has a huge potential. This kind of games have low system requirements, a fairly low price, a small download size, simple rules that are easy to learn, etc... They are not for hardcore gamers, but for everyone else.
Today, I've downloaded the trial version of PopCap's latest game: Talismania. The demo version lets you play for 60 minutes, and I must admit: those 60 minutes flew by. They managed to produce another awesome game, with nice graphics, great music and simple but addictive gameplay. I suggest you download the trial version (a small 12.6 MB download) and try it out.
PS: I'm not sponsored by PopCap, or in anyway affiliated. I'm just a fan.
