Zero Punctuation's Adventure Games
Most people who know who Zero Punctuation is most likely know that he made games before he became a game reviewer (I actually knew about Zero Punctuation before he became Zero Punctuation), if not then listen up. He created a certain series of point and click adventures titled the Chzo Mythos. I have played and beaten 2 Entries in the series and I consider them to be phenomenal games with very strong character development, and fantastic plot lines (often with unexpected and unwarranted plot twists). There have been other entries, but I haven't played them yet, but I intend to start playing right now. Go to
Zero Punctuation's site and click on the game tabs to download the games for free.
If you like those games and want to play more games like them, then I strongly suggest you play
the Ben Jordan series of Point and Click Adventures which are equally just as great.
