I loved the art direction in Bioshock Infinite - and the saturated colours and quasi-cartoony character models were a pleasant departure from the current trend of ultra-realistic GRITTY MILITARY SHOOTER. Infinite probably had the most gorgeous and unique backdrops I've encountered in a video-game - it's evident that the developers invested a lot more care on design and detail than the majority of AAA titles floating around the market.
