Well I just finished Killzone 3 and most of the time I just got bored shooting with same frikkin riffle.It had only 1 gun I liked to use (nail gun). Then I looked at my game collection and its pretty much all the same..Dead Space  and Bioshock have pretty good and interesting waepons but they arent those kind of shooters where you need to shoot 150 enemies in few mins. Actually I even stopped playing Uncharted 2 since guns were getting boring...I wonder will Uncharted 3 be just with same waepons.

But for some reason I didin't get bored at weapons in Call of duty..Hmm.

I remember back in old days playing Red Faction against bots more than I have played any fps game in this gen.it had at least 10 unique waepons and you could even shoot yourself a tunnel..Of course I cant think o fplaying game like Metal gear solid with Ratchet and clank waepons, but you could think of something interesting for each game.

Resistance has some good orginal ideas and I'm waiting for Resistance 3 much more now, after dissapointing in Resistance 2 and Killzone 3.

In uncharted 2 i hardly used weapons, I just run around breaking necks and if an weapon is required, nothing an RPG or grenade launcher cant handle. 

but yes more interesting weapons is needed. Killzone 3 had all the oppunities to give an awesome weapon but nope same old crap. 

Personally I do not mind generic weapons, as long as the action is good and the stroy thrilling. I remember with great fondness the shotgun in the original Doom!

well i was glad they didn't make all fake alien weapons because the weapons they had are not real but they are not far fetched in a sense you forget that you are the humans, with the add of a couple of guns that are alien like, i liked it. the only problem i had with the weapons is they needed the bolt gun, the grenade launcher, and another sniper and rocket launcher and maybe one more type of assault rifle.

I loved the feal of the weapons in Killzone 3 they have a very violent feel and sound to them. Most of what you say sounds like a personal problem, to be honest. There are lots of gamers who don't actually enjoy the games they play because they are too caught up in meaningless details. 

You probably sit there and play a game and the whole time you are getting upset or bored because it isn't enough like some other game. Why bother?  

i would like to point out that BFBC2 had pretty same old same old weapons but out of the same old same old, i reguard them the best of them all, probably the best regular guns ever. Why? the Sound. The Sound was executed so good it got rid of the toy weak sound and gave them the grunt and power that is lost in gun games. It was so much more statifying shooting in BFBC2 than the toy sounding guns of Black ops. 

If you want interesting weapons then just wait for Duke Nukem: Forever and Deus Ex: Human Revolution.

Just play Borderlands, it has a bazillion guns. And the game is very fun.
