Picked up Point Lookout and Broken Steel exp packs so I could continue my Fallout 3 adventures. Mostly wanted the additional levels and game not ending after finish OG story. Decent enough fun and enough levels that taking the explorer perk to show all map spots wasn't a big deal.
DLC Mods: Point Lookout Lower Health, Point Lookout Made Easy
Other Mods: Bobbleheads, Speedmod
Enjoyed the DLC but didn't like the difficulty of Point Lookout so modded it. Odd to have skinny humanoids with crappy guns cause so much damage.
