Yeah out of many final fights you know you get to the end and have to take on the guy who has given you a lot of trouble and you usually hope that it is a good fight but some games have fights that are just really boring or are just too easy in the final moments of a game.
Here is a few I say:
Zelda OOT: Ganon, The music and everything else is incredible in the final fight even how you need to start off without the master sword and work your way around. Only sad part is even if you have the biggoron sword or not all you had to do is roll under him and hit his tail until you can get the master sword again and just kill him off with that. The final fight was nice but too easy and Ganon did not even get the tricks and powers he got in the past games even when he was close to death. The final strike part though was nice when imprisoning him.
Halo 3: Yeah what I liked about Halo 2 was that Tarturus was acutally a challenge and even in co-op there was a major call for team work to take the brute down, it was a multi-leveled arena and he could only be hurt every few moments. In halo 3 we end up fighting Gulity Spark, oh out of all weapons he can withstand bullets, rockets, and tank shells but not a spartan laser, WTF? Oh now we get to kill the pest. He is way to easy even with many skulls on. What is stupid is that even in co-op just 1 person does the work while the others just wait until that guy is done. I mean I think it would have been much cooler to fight the gravemind, I mean he does not even appear in Halo 3, only his tendrils appear. I mean I think that if it was a huge mutation of the gravemind around the control room stopping the firing sequence then it would have been a challenge as you grenade and rocket him into oblivion and activate the ring as he dies and run after that but no we fight a stupid monitor that only shoots a beam that has little effect on us.
