Worth what exactly

yuo can play TF 2 gmae if you have specific opnion on not-tf2 thing........enjoy

worth playing

this is the question you ask for pay to play games

just install it and play. did you have fun? if yes, play it again. if no, don't play it again

???

the fact that multiple people are responding to your question quickly shows the community is still active. besides that, i dont know what would make it "not worth playing". as drifta said, just play and see if you enjoy it? if you mean is it worth trying to make an actual career as a pro tf2 player than the answer is a hard no though.

for anything more than pubs with friends, no of course not

Pubs are shit cause of all the cheat bots but other stuff is still good.

And cheater-free pubs are obviously still good.

but where can I play 6s, in a casual way. Is there anywhere else to play other than pugchamp?

tf2center is still active (and still as bad as you'll remember it) but if you want casual 6s that'll be what you're looking for.

in-game comp matchmaking is still forcing graphics settings so it has a very low player count.

casual pubs have some cheaters going around every now and then, but it's not as big of an issue as people make it out to be

Not much has changed the past 2 years. It's 99% the same as when you stopped. If you stopped before the pyro update:
Pyro airblast is still fucked, just in different ways
New pyro unlocks other than Dragon's Fury are quite bad and are whitelisted in 6s so for you that might not even be relevant
