Some of the end bosses in Radiant Silvergun are HARD!!! Like the Phoenix, once he lights up - geez! That game is so fun, it makes me want to marry my friend that owns it, just so I'll have access to it always. Not that it's a guarantee, but better than nothing!

Me, dammit!
But since I know that's not true, I'll say last boss from Baldur's Gate. All but my main character died, and he only lived because of a potion of speed (or many) - anyway, that's what I say.
If not... me! *sigh* I know, nevermind...
