This was also during the peak "the only two colors are brown and off-brown" of this console generation.
It's a shame because games that took advantage of the hardware (not necessarily saying full power- just using the advancements since the previous generation) produced some gorgeous games like Flower, Super Stardust HD, Journey, the Ratchet and Clank Future series, and LittleBigPlanet (among many more).
Sometimes people complain about the color variety in modern games but I'll take it every time over the PS3/360 gens.
