Ahhh yes, the "generic" game. Ones that re-use elements that we've seen over and over. True enough this is an irritating problem, but I don't think the problem is re-used game mechanics, which Yahtzee seems to focus on in this review. Instead, I think the problem is re-used storylines, which is something he's talked about before, but not in this particular review. Yes, it's irritating as hell to have to hear about yet another brooding military type in the middle of some God damn warzone or on a secret mission where his superiors hid the truth from him and he's the last member of his team not to get turned into sausage filling. Yahtzee's also right about some of the characters, like the guy you thought was your friend that stabs you in the back, or the only woman in the game is destined to be your shipoopi.
For me re-using certain types of mechanics isn't that big a deal. Sure I like to see new mechanics (who doesn't?), but just because a lot of games have you hiding behind cover doesn't mean it's a bad idea. It's a GREAT one, if you were actually getting shot at in real life, would you really be running from size to side while waving an assault rifle around like an epileptic? NO, you'd get your ass behind the nearest solid object and wait for the best time to shoot back! Limited number of guns to carry? That's not bad either, when properly used. It requires an extra element of thought to gameplay, requiring you to try and think ahead about what situations you're likely to wind up in and what weapons would be the most effective.
Now I will say this much about "generic" gameplay features; not all of them go together. Cover-taking, for example, is rendered pointless with regenerating health. Iron sight aiming is fun, but only if the enemies don't have instant 100 percent accuracy for any player not running around like he's got ants in his jock strap.
In closing, I personally think the generic plot devices are the bigger problem than the generic game mechanics. The sooner game developers realize that a lot of people not in the military know the right end of a gun and how to not get their asses turned into lunch meat at the first sign of a terrorist attack, zombie apocalypse or alien invasion, the better.
