Thanks for that.Because you're a good among men??
I'm only kidding a little. How? How did you do that in this day and age? I was really proud that I held a group together long enough to run all of the Curse of the Crimson Throne adventure path, which took about two years. I'm still proud, but 2 is a lot less than 17. Or 10 or 12. I'm deeply impressed.

The trick is to have a stable group of friends who aren't planning on moving away, and to stay in one place yourself.
I remember that fight as well, but not nearly as fondly as you. My players tried every obvious "what if" that the module doesn't answer:I'm glad Keep on the Shadowfell worked out for you. What's maybe unfortunate is that the best part of the adventure, as I remember, was the epic fight with the boss at the very end -- and I'm not sure that battle would be nearly as good outside of 4e. It made great use of terrain in the way that was uniquely exploitable in 4e. I still remember that fight almost two decades later, so that was a doozy. Hope it was as good for you!
--- they tried attacking the tentacled thingy coming in through the portal in hopes of slowing its progress; it's given no write-up of any kind (the module just blithely assumes the PCs will ignore it) so I had to make up some stats on the fly
--- one PC tried going through the portal to attack the tentacled thingy from behind (!); the words don't say anything about this but the picture shows the tentacles completely blocking the opening, so based on that I told him he was out of luck
--- some of the PCs wanted to shut the gate down while others wanted to open it up and let the tentacled thingy in (either naively thinking they could kill it or hoping to gain a stupidly-powerful friend, I'm still not sure which to this day); the module gives no mechanism for controlling the gate either before or after the BBEG is killed, so I had to invent one on the fly
There was some other headache came up during that combat as well but - perhaps mercifully - I've forgotten the details now.
