Just finished Sleeping Dogs last night. I know I'm LTTP, but damn that game was soooo good.
I stopped playing GTA V after I started Sleeping Dogs as the game-play is just so much better. I loved the fighting mechanics. Driving was a lot more arcade like than GTA V, but a lot more fun. And the shooting just felt better. Shen is also a better protagonist than all three characters in GTA V. Can't wait for Triad Wars.
I'll give it that Rockstar has higher production values (due mostly to having a bigger budget) and that they build open world environments like no other, but they are sorely lacking in game-play and providing likable characters.
