Up until now I have almost exclusively played CoD games except for a brief stint in Halo 3 (would have kept playing but my friend wanted the game back)... I admit they have their faults (lots of them (especially Black Ops)) but they were entertaining. I enjoy this game quite a bit but the more I run into these issues, the more I feel like going back to Black Ops... I mean, it's a piece of ****, but at least it's a polished piece of ****.
I don't doubt that something will be done over time to fix this game, but so far the frustrations outweigh the fun. I really do enjoy the game, when it works semi-decently. I will continue to play, but each time I encounter one of these issues, it takes a little bit of the fun away, and I inevitably end up putting that wretched Black Ops disc back into my 360.
The only real conclusion I have come to thus far is that after both disappointments with MW2/BO and Crysis 2, I think I'll turn to Battlefield 3 to hopefully redeem the FPS console genre for me. I don't hold much stock in MW3. With all the developer issues/legal trouble, I feel it will be rushed.
Anyway, these are just my thoughts... take them for what they're worth (not much).
