Was having a really hard time getting back into Fallout 3 with the DLC. Started when I loaded my last wasteland save and last level 20 save because I deleted the rest. The save was close to where I took out my last Giant Mutant and with the new DLC a whole bunch of AK47 wielding mutants spawned in the area and kept immediately shooting me up. There was 6 of them and I kept dying almost instantly at loading. After 7-8 deaths was able to take cover behind a bus, climbed onto the roof of the bus and jumped over the enemies to escape into a nearby building. I thought I was safe.
I saved again and decided to wait for a few hours inside so the enemies would go away outside.... Nope. All six rushed inside and killed me within seconds. Lol.
Loaded up the new save and this time just as the enemies were all loading through the door I rushed out and quickly activated my PIP boy for instant travel. Hit the 'yes' button to travel to Megaton just in time as the enemies were loading back into the outside area.
Thus begins my nightmare with the DLC. Main reason I'm having so much trouble is because I forget how to play the game. I sold off items that I used for repair for caps, all my best weapons and armor are nearly broken, I had been struggling. Barely cleared the first mission of Broken Steel, had to use a Fat Boy missile to clear the final room. I think I'm finally getting the hang of things again, but I wish this DLC had come out sooner. Forgetting how to play and getting frustrated has made me question how I even liked this game in the first place.
Only experienced one glitch so far where an NPC player froze and I couldn't talk to him to activate the next mission. Otherwise, gameplay has been smooth and I think I'm in good shape now as I've got over the learning curve again.
