Yeah, I did that "All hobgoblins shoot at one player" too. Granted, they were standing in a line with a seargant next to them giving orders... yet, it was a bit too much.
Geesh, I can't tell you how glad I am that I didn't read a story about myself here yet.
1. Story:
I told this one here more than once. One of my favorite examples for railroading and why I don't like it. That was a convention game where you had to sign up in a list and the DM had a page of houserules and his own feats attached. Plus a page about the adventure beginnging... something like: We carry a message of uttermost importance to the king. We are in the wilderness and there are riders looking for us nearly all around us. Yes, they see us.
Level 4 char creation. One of the houserules was Limp (more a trait): Movement 5ft as full round action, one mental attribute +2. Another one gave +10 ft movement (Fleet of Foot).
Well. We gathered some players, one limp gnome illusionist, one limp kobold sorcerer, both sitting in the backpack of a halforc barbarian with Run and Fleet of Foot. 5 times 50ft > 4 times 60 ft (horses). Later one human cleric joined, but the gnome knew Reduce Person (very useful to carry the cleric in one free hand).
Well. Long story short: DM went crazy because we didn't get caught like he planned to, our halforc outran the riders. He wanted us to break out of the jail without weapons and armors (in some strange way including the guard and some princess and some old prophecy). We simply attacked the fortress with our full equipment (both spellcasters had bought a wand of Magic Missile) and burnt it to the ground, rescued the princess and killed all bad boys
We had a lot of fun, the DM was sick about "powergamers" and CRPG dudes.
next story next time.
