Really, I have been playing a lot of shooter games lately, CoD series, Bioshock, Lost Planet 1-2, and all of them are just the same thing with different storylines. There are still some fun and original ones out there, I'll admit that, but those are the ones that almost no one plays due to their difficulty and/or the fact they are made by a second-hand developer.
A lot of them times I actually find myself setting the difficulty to the easiest settings because I don't feel like trying so hard to get through one wave of enemies just to do it again in another 5 seconds. The only interesting parts of these games are the storylines, really. I mean, Bioshock is so goddamn interesting but the gameplay is so goddamn boring, run around for 20 minuets searching every room for stuff, then go and fight five crazy stuffs, maybe run into a big daddy, run around in circles shooting him with electric buck, get little sister. I basically summed up the whole game right there, its the same thing over and over with a very intriguing storyline.
Games that ARE good, like Ghost Recon: Advanced Warfighter, all require some level of skill and strategy. If you play the hardest difficulty on GRAW 2, you can't just run around the field shooting like a crazy motherforgeter lobbing grenades every whichway then taking cover, regaining health and doing it again. You have to think about each battle carefully, gauging how you should move your squad, how many guys you can take out with one grenade, all that. It's difficult, you have to think, you don't just point and shoot. This is why I also find strategy games so fun because you can't win (usually) by doing the same thing every time.
tl;dr videogame companies need to get their act together and make harder shooters that require more thinking.
