Started playing Fallout 3 after the itch created by Fallout 4. I picked up Fallout 3 Wanderers Edition mod, FWE, from Nexus along with a few of the mods listed on the FWE page. The mod makes the game challenging to the point that certain enemies are impossible to defeat early in the game. It also provides an alternative starting point rather than the Vault while still keeping the basic storyline intact and playable. My first character was one of the lawful groups, forgot the name, styled as cowboys. Upon leaving the starting building a pack of feral dogs rushed me. I paniced considering it was a huge pack, about 8, due to a secondary mod listed on the FWE page. These dogs ran right by me and attacked the small group of Brahmin. After killing the Brahmin the pack took off without even attacking me. After all of this I was still a foot from the building door wondering what the heck just happened. Later on after about a hour or so of game play I explored one of the areas with the Mutant Behemoths as one of the mods made these npcs more challenging. So I wanted to see for myself how challenging. I explored for a while without finding one. Just before leaving the area I heard a sound. I stopped, did a 180, just to see a Behemoth smash my face in, 1 shot, with a street lamp. Those Behemoths are stealthier than I thought for something over 10 feet tall. Now I want to find a Deathclaw just to see what the mods have done to these beasts.
I would recommend the mods for anyone wanting a more challenging Fallout 3 experience.
