I'd like more examples this is just off the top of my head ATM
No actual spoilers in my post expect for videos, but majority of these games are old.
I mean when I say this,lately some games final battle has been letting me down. They don't have that same "oh shit hes still alive!?!?" bullshit like older games.
FF was a pro at last bosses,you never knew when they were dead.
A few of games could have had better ending battles/scenes off the top of my head:
Halo 3 - last level is just fight the oracle and a ****ing car ride :| Fable 2 - good game but nothing epic to fight, just the same troll over and over Fallout 3 - to good for such a boring ending Assassins creed 1-2 - I know you cant do much for a boss but I expect more Oblivion - can't remember exactly just remember it lacked.
In the middle: Boarder lands - fun but easy DOA4 - fun but cheated hard as **** but made you play so hard to win. GTA4 - meh........ Tales of Vesperia - to predictable
Good endings: Mass effect 1 - just barely made this Mass effect 2 - It was easy but soooooooooo fun/cool Call of duty MW:2 - This here be some fast paced action, well for me atleast.
