You want play with A.I. or other person on net?
If want play online with other human players, maybe QQ games, got
mahjong, poker, snooker/pool..... etc.
If play single player, download "Ming Xin San Que Yi", which is
quite fun to hear those dialouge, and see the cartoon
pictures.
For something more "tweakable", go for "fourwinds"(Not sure if the
name is correct), you get to play with many possible opiton to
change the rules based on your preference.
