Well, got around 1.5 days played on this game.
First things first, the gunplay and general game slow blows away MW2. This game is about the players and their guns, Mw2 was about the killstreaks and the campers who used them. Its different in design. I MUCH MUCH MUCH prefer Black ops.
Now, the major issue right now is SEVERE lag and Party issues. The first week this game came out, it wasnt even 1/5th as bad as it is now. Last 2 days, with parties in the size of 2-4 people, its just gotten so bad that its either always a) disconnect, b) someone gets kicked, c) game starts and we're on opposite teams, d) endless loading and forced to go to XMB, e) people end up in different lobbies, etc etc.
Its basically a huge nightmare to play this game online. Mw2 had no such issues by this same time frame we're at, and it comes down to netcode and talent. I understand that MW2 code was withheld from Treyarch, but frackin a, this is what public betas are for. Now, the other major issue that just gets WORSE with time, is the lag. I get so much lag these days its absurd. I shoot half a clip at the guy, hitmarkers the entire time, then he turns around and kills me. Watching killcam, i shot 1 single time and he turned around and killed me. Its just idiotic and not fun at all.
At this point, other then gun game, i dont know of a single reason to play it anymore. The lag is unbearable and shouldnt have to be suffered by anyone. MW2 had major lag issues as well, but this is about the same or worse most of the time now. At launch, it wasnt anywhere near as bad.
I need to take a break from the game since its driving me into a heart attack. My K/D is 1.50 so its not like i suck or anything.
