The XBox's "Luigi's Mansion"
That's not to say that "GbtG" is boring or non-entertaining. But the game is basically a fighting game first, and an adventure game second. By contrast, "LM" seemed to me more of an adventure game first, and a beat-em-up second. Maybe style isn't better than the other, and maybe it just depend on what you're in the mood for. The repetitiveness is the single major flaw in "GbtG". The other flaw is common to most games, so I won't hold it against this one, and that is the camera control. Sometimes objects would block my view of the fighting, which of course is very frustrating and makes the game more difficult. But I've yet to see a game with perfect camera control, so moving on...
All that said, I still give this game an 8/10 score, which means it has to have some highly redeeming values. And it does! The game oozes quality in every other aspect, from the animation, the art, the sound, and the characters; to the comic-book style story progression, all of which give it lots of personality. The whole game is very humorous, and I found myself laughing a lot as I was bashing my way through the levels. Kicking a zombie pirate in his, uh, thingies repeatedly and hearing him go "Arrrr!" is just hilarious. Punting little purple imps as if they were footballs makes me crack up. And going all WWF on the Grim Reaper, including elbow drops, stomps, and groin kicks, is so surreal it's downright funny! To me, personality and high quality execution is very important, so some weaknesses in gameplay can be forgiven. This game has lots of humor and personality, along with the story and characters, and this made me want to finish the game. Which I did, and which was not an easy task!
Which brings me to give you some hints which may help you complete the many difficult and frustrating levels. One thing to remember, and I found this out by accident, is that in levels with a breakable window, the Reaper can be banished from that level. To do this, lure the Reaper toward the window, and stun him, then proceed to bash him until he's knocked out the window. Ta-daa! No more Reaper, at least for that level, unless you die and have to do it over again. To stun the Reaper so that he can't touch you, it's best to kick someone into him, which gives you a second or two to start laying into him. It's tricky, but worth it if the Reaper keeps bugging you (and bug you he will, constantly!) This also works with mummies, who are only killable with fire.
Another way to finish some seemingly-impossible level is to let the Reaper do it for you. By this I mean that if you're having trouble knocking out a ghoulie, bring on the Reaper, let him come after you, and place the ghoulie between you and the Reaper. The Reaper will kill him for you with a single touch. If you find yourself surrounded by ghoulies, and you often will, you can place yourself among them, dodge their attacks, and let them attack each other. This is very helpful in levels where you're only allowed a limited number of attacks.
Many objects have special power-ups, so as you go through a room, bash any and all objects to find them. Use them wisely, and this can make the difference between beating a level, and...well, not beating the level.
Now if you don't care much about repetitiveness, you will enjoy "GbtG", so I recommend at least giving it a chance. I got about 10.5 hours out of it, and was satisfied when I was finished.
