I can't decide with TF2 whether I'm still into it at the moment... I used to play it loads from the early days and really enjoyed it but something feels like it's changed, maybe just the huge influx of weapons and items as mentioned above
The original noble design choice Valve went with, making the classes easy to identify from a distance or at a glance, is sort of ruined when you originally would have:
"Oh here comes a Pyro/Heavy/Demo/whatever, they will be using one of 2 or 3 possible weapons so I should try to approach or deal with them like this..."
to now:
"Oh here comes a Pyro/Heavy/Demo/whatever, who knows what random gimmicky items they will be using so may as well just charge into the spamfest and hope that by trial and error I can start to learn which player-name is using which specific weapon"
I don't really mind the customisation cosmetic items so much... it's a bit of a fun and can be enjoyable, but it doesn't impact on the gameplay (other than it being such a focus of so many player's attention now rather than the actual game)
I have to agree. I used to love TF2, it was easily one of my favorite games (I have over 900 hours in game...) but then they went a bit too far with all of the weapon types.
As others have said, when they first brought out new variations of guns, it was a nice addition. It allowed for a slightly different strategy, but then came along user created content which opened the flood gates to the endless stream of random weapons.
