I'm not a fan of this old shooter revival movement.
Don't get me wrong, I grew up with games like quake, doom, goldeneye, perfect dark, Turok etc. And I really had a blast over the years playing them (Mmm I still remember all the time I put in unlocking absolutely everything in both Perfect Dark and goldeneye). But I went back and played everything I used to love for the old nostalgia feeling (I even gave serious sam a shot the other week), and quite frankly those games bore me to death now.
Walk forward, point, shoot. Just make sure you do the pointing part as fast as you can, and that's about it.
Regenerating health, a cover system and what have you serve to add more depth and variety than the above to your little encounters. Of course that's provided they're designed and integrated well, which in many cases they aren't, and are indeed just checking of a list of standard features to which the developers are begrudgingly bound.
But there'll always be bad games out there, what matters is that the ones that do it well provide a much deeper, strategic form of game-play than the oldies. And thus to me at least, are much more entertaining to play despite the fact they might not be as cool/fun to look at or talk about (what with the whole generic space marine in the future setting thing we have going on).
As boring as the artistic direction and storylines are in gears of war or crysis or left 4 dead, I have a hell of a lot more fun approaching each situation differently and actually having to think about how to handle each enemy creatively (relatively, for action type games anyway) Than I do running into each new area doing the exact same "Shoot everything in front of you really fast" routine.
