This generation should be called the brown generation
All the games use the same brown pallet that starts to get annoying.
Not just the million shades of brown, but greys and greens as well.
When it comes to much of the big budget developed titles with good so-called photo-realistic graphics, its always just the same gritty shades of these three colours, ESPECIALLY for FPS games.
Sure whilst I do enjoy many different games regardless, I tend to have more fun on quirky games with "kiddy graphics" (Nintendo DS especially), or pretty much most Japanese-developed games with their Anime-style look. I rather have my own eyes see lots of bright rainbow coloured visuals than being stuck in the drab world of the browns, greys and greens. Otherwise I may as well just be colour blind and it won't matter.
Graphics and artstyle direction is one of the most important things for me this generation and for the past few years, it has been very disappointing.
