Spanish Fury!

A very good game (or series of games) I think Siege (which was published in 2000/2001 I believe not 2004) is one of the best on the topic of Renaissance Siege warfare (ok the only one on the topic). The graphics are great, you don't need miniatures, and it's FUN.

Superb period-specific rules for the Dutch Revolt, French Wars of Religion, and Anglo-Spanish Wars of the later 16th century. Battles, sieges, campaigns, naval combat, skirmishes, duels. Free downloads from The Perfect Captain website.

Fun game.

Excellent period-specific rules for the time between renaissance and age of reason. This is an important period ignored by most wargame makers. Also, this is completely free.
