Devil May Cry 4 has some really nice bossbattles - esspecially with Nero which has the fatality (the demonic arm) makes some really nice and cinematic scenes.
Half-life 1 mostly has good bossbattles except the last.
Prince of Persia The Two Thrones has really good ones.
Prototype last bossbattle was godlike for me... it was such a close defeat.
Max Payne 2's was legendary.
Portal has Half-lifey bb (which are unorthodoxly good)
Psychonauts bossbattles were mostly good except the last.
Metal Slug (on PS1) was epic.
American McGgee?s Alice
Chtulu saves the World loved the bossbattles (were mostly playing the game for them and the humour)
etc.
