'Puerto Rico' is produced under license in USA by a company called 'Rio
Grande Games'. Many online stores sell the game (it is not very cheap,
around 50 US$), by example at Funagain games, but it appears it is not
easely found in some popular stores, the game does not seem to be
taylor-made for the American taste, surely by some reasons I have briefly
shown, between other reasons. It is a 3-5 players game, but there are
unofficial rules for 2 players. The game feels different whne you play it
with 3, 4 or 5 players, strategy must change according the number of
players. The rules in English can be downloaded at boardgamegeek.com, in
the section 'files' of the Puerto Rico page. At this site, you can also
download a very, very strong free PR program called 'Evolver', wrote in
EXCEL!, although with crude but decent interface, and with AI based on
genetic programming techniques, it learns in each game it plays, so it is
desiderable to keep the growing database of the excel program. To run it,
you must weaken the Excel controls over macros, the macros need to be
habilitated for proper run. This is the section where you can download the
amazing Evolver: http://www.bggfiles.com/viewfile.php3?fileid=8766
