I finished Sleeping Dogs last night and I'm pleased to say it was pretty much as good as people say it was. The setting is fantastic, the combat is cool, the story is varied and unpredictable enough, and the side-mission/collectables stuff is really rather addictive. I got it on a glitched GMG deal over the Xmas sale and I'm more than happy with the purchase. Yes, the missions get a little repetitive in the middle, but overall it's an excellent game. There's plenty of copies available in the Steam trade thread for about $10 and it's well worth it, in my opinion.Spoiler
I'm planning on playing through Deadlight now. This isn't what I expected. I assumed it was a side-scrolling shooty thingy. Doesn't seem that straight-forward. I'm liking it though, very moody.
While I thought Sleeping Dogs is a good game, the main issues I had with it were lack of variety, and lack of challenge. The game is too easy, you can basically counter everything easily (melee) and use slow-mo for gun fights. There isn't one single thing I could think of in the game that had any challenge to it, which doesn't seem to be brought up much.
