Like how the weapon/vehicle/AI models were, how the scenery was, the art. The skyboxes were the best in the series and the visuals were very clean/polished and colourful too! Not which looks more realistic. Not how good the graphics were. Which looked the best in your opinion? State why too. IMO it's Halo 3. Although many people claimed it for being too "cartoony".I thought it was beautiful. Look at Last resort and Stand off and high ground. Obviously there are more beautiful looking maps in Halo 3 but these are some of my favourites. Halo 2 was close but Halo 3 was better. Halo 1, Reach and CEA were excellent too IMO. But the Halo 4 art style...alright. It doesn't really look like Halo though imo. I know it sounds stupid but it looks toooo scifi, over the top. The brightness of the art style they got right though lol but other than a FEW guns and vehicles and MC and Cortana people can say it doesn't look like a Halo game..oh and this kinda goes for the sound effects too though. Graphics are obviously the best though. I hope Halo 5 has a very similar art style to Halo 3 but obviously with a graphical upgrade obviously. This video further proves why I like [url=http://www.youtube.com/watch?v=RWTbZ3Rbm54]halo 3's[/url] art style/graphic style the best.
