When you've got the right people it's far more fun enjoying some games locally than it is over the internet. Then again, it's just as easy to find enjoyment with the same people over the internet for me at least, so I guess I don't miss LAN parties too much.
I find it always way more fun to play with my friends locally than playing online with them. It's just different when you get together in a place.
I totally agree. I can say that I do miss everyone getting their computers together for a StarCraft LAN. It was fun party environment that just cannot be reproduced online and chatting on Skype. Yes, you can just physically go to your place with your rig and then do most of your gaming online together, but there was still something fun about setting it all up back then.
