First let me state this, 90% of shooting games I have played, I couldn't stand. They were all generic, the same shit just a different toilet. Modern warfare, call of duty, and everything else you can mention even halo (one of the few shooters I actually enjoy.) Note this is all my personal opinion so any fan boys out there who's going to get offended, squash it.
I honestly don't see how people flock to these games so fast, especially those that are military themed games. I actually looked to expect games like call of duty, and modern warfare to hole both a strong strategic element along with a mindless shooter, but it disappoints me every time I play it or even seen it played. The new call of duty black ops is no different from what I have seen and played. It did nothing but follow the same generic (walk around , bang bang your dead) set up I see in almost every fps. I went into it optimistically really giving it the benefit of the doubt, and the more I played it, the more I was disappointed finding spots and areas, that in team game that could have been used for trenches and defensive set ups, or openings in walls that were just the right size for moving around undetected, just to end up finding out the developers didn't bother enough to actually add these separate elements for a more dynamic game play, and not to mention more interesting.
Maybe its just me, I have a strong love for rpg, and rts. With that noted I did say I loved halo. When I played halo it held a certain amount of chaos which I played a rts (when two armies at their strongest points clashed.) many times I ended up in long drawn out battles where one wrong move could decide the out come of the confrontation. Halo reach Again this is just my personal feeling towards shooters lately.
