Halo 3 is fail. Graphics look pretty much the same as Halo 2 exept maybe more polygons and smoother textures. Guns look the same, lighting and colors look exactly the same, animations look the same...For $60 you are pretty much buying an expansion pack. Shit you could buy a case of beer, a bottle of wiskey and a cooler to put it in for that much money. But I guess as long as people play them bungie will continue to make shit loads of money and will continue to make more unoriginal games.
Halo was a good game because it was fresh. It had great graphics and the multi player mode was amazing. I just think they should have been a little more creative when they made the other halo games.
I know this is slightly off topic to this, but I felt like saying it.
It's not all about the graphics. Gameplay itself is probably the most important factor. Take for example "Driv3r" When it came out, it had quite decent graphics, but was an absolutly horrific game. Whilst on the other hand when "GTA: San Andreas" came out, it didn't have the best graphics and yet ws top of the charts for god knows how many months.
So I don't really care if the graphics aren't any better (In my opinion, I thought they were great), Halo 3 is still an excellent game to play and is great fun to play online.
