As a guy who played the entire series on PC, it goes without say that I got this one the day it came out. Regrets? Heck no! GR2 is simplified compared to the older version, meaning that you don't need to micromanage your team(s). Some people may hate that fact but I'm just fine with it since it improves the action for me.
The gunnery is excellent. Accuracy is the name of the game, as is tactical intelligence.
