This is a matter of opinion it depends on what you like Modern Warfare 2 is a more fast paced couple shot kill game. Halo Reach is a little slower and isn't a game where you shoot two to three times and the player dies. It is really different in many other ways though. ANSWER : It doesn't matter about shooting , its the campaign and multiplayer. The campaign is great for Halo Reach and more action while the multiplayer is also great . The ranking for Halo Reach is hard work. MW2 is just duck and shoot in my opinion
Depends on what time of day it is. Halo reach is a pretty old game now so don't a huge amount of players on it.
Yes you can. I saw that its better than playing it on the xbox. But multiplayer is a little hard to get for many people.
