I'd rather break the game in half and use the jagged edge to clean myself with than play the game. I can't believe people stuck with that game a full year and won't even stick with this game a full week.
I can see your frustration and maybe I can help you to understand where I'm coming from.
I didn't play Cod4, or WaW. I bought MW2 and then someone lent me Cod4 to try out the campaign to see what I'd been missing.
I liked MW2 as I had no other game to reference it against.
Save Killzone 2 and MGS4 and neither of those really count, right?
As it was the only one I have tried, I have been through a steep learning curve of getting my ass handed to me on a million occasions and only fairly recently have I started getting positive match results after a long time playing.
I appreciate it for what it has taught me and how I have had to sharpen up to even get through a match. Even now, ask some fellow GTP'ers and they will tell you how sucky I am.
What I haven't done is play a Treyarch title before.
With only MW2 to use as a comparison, I find Black Ops disturbing in a few areas, which I have mentioned before; graphics, party play, hit detection and so forth. I'm sure all these will be patched, or have been already, but for me, it just didn't feel right.
Now here is my point, which I tried to make earlier:
I appreciate that it must take a better gamer than me to succeed in this game, and I bow to your collective FPS prowess, but I do not have the time, patience or controllers to see me through the learning curve on this game, and so I have returned it after one week.
This would be the first time I have done such a thing, as usually I make an informed choice before purchasing a game, but I took the game to be the logical progression in the series and so bought it based on previous experience of MW2, and what I feel I got was a backward step wrapped in cellophane. That's my opinion.
I'm sure the only reason why I don't like it, is because
it's too hard for me, and I don't like playing a game that I know I will never commit to becoming very good at.
So, in short, I suck at BO, I don't suck so badly at MW2 and I think I'll stick to that one where at least I can get a predator missile every now and then.
