I like it better than MW2. The things I hated about MW2 was the quick scope crap. You almost always died from 1 shot even somewhere stupid like the foot. I hated the fact that people could hide in areas where it was imppossible to kill them but they can kill you perfectly from a far distance. Not everyone snipes. I hated the rooftops bc people would just sit on the upper level or the roof and snipe all day and you couldn't kill them, getting like 50-3. There are almost no places like that in BO and I like that.
I think it is better that it takes more damage to kill enemies, its alittle more realistic but sometimes it does piss me off when I hit someone 6 times and they kill me first anyways. It is one or the other I guess but Ill take it. I also like the fact that extra damage is out, but I think Hardened Pro gives extra damage?? Commando was good but there were some IMPOSSIBLE kils from way far away. I like the fact that you can have a granade and a claymore, AND flashbangs, etc
There are alot of new features I like about BO. I like the new wualifications for going Pro. Its not so easy to get. I like the amount of options such as creating emblems (very nice add-on), face paint, lens color/emblem, more guns, good kilstreaks, and more. I like that you have to buy stuff too. Its not hard but it may take some time so its not so easy. I like the new levels too for the most part. They are alittle bit griddy and mazey I will give you that, but i think that solves the problem of what I said earlier. I also like Zombies. I think Campaign is great too!!
Like any game out there, there are problems. I think the connection thing is a hug issue. Sometimes I will get kicked out of a party for no reason and can't rejoin. Games don't start, they just go back to the lobby multiple times in a row. Sometimes it is annoying that the games start quickly because I dont have time to change settings for a certain level. Sometimes when migrating to a new host, my PS3 freezes and I have to turn it off.
But overall, I hated MW2 to death. I like BO much better and I actually have more kills than deaths this time

I think they solved alot of problems from MW2 and I thank them.
