Well I've played 4 separate characters up to level 20 now.
Finished the main quest 4 different ways. (freeplay mod)
Played it as good, bad, and neutral, and various levels of each.
I'm playing it on hardest settings now, experimenting with new hideouts, weapons, and settings.
I'm averaging 40 hours a week in Fallout3, and have been since it was released.
I'm still finding new quests, new locations, new ways of playing the game.
This character has father issues, so he's not looking for dad at all.
He didn't like the looks of Burke, so he just walked up and killed him.
Then disarmed the bomb in megaton just for spite. Then when Tenpenny sicked the talon mercs on him
walked to tenpenny tower and killed the old man. Lots of side quests but dear old dad is on his own.
Current favorite mods.
Xrepair (makes keeping weapons in repair a bunch easier, can use wrench's and scrap iron)
Better Regulator Duster (brings the regulator duster up to a more reasonable armor level)
Echo Battery charger (adds a "workbench" that lets you turn E cells into MF cells, & vice versa.
Slaver stick (works better than the mesmetron, needs no ammo, lighter)
The Hideout (puts a garage hideout, with hidden vault next to megaton, very handy, full of goodies)
I have to give the good folks at Fallout Nexus a nod.
They have IMO the most mods, and the best, and they are easy to browse.
http://www.fallout3nexus.com/downloads/categories.phpBrowse catagorys, then once the category loads I sort by upload date, descending so I see newest mods first.
I really like how people in the game treat you differently depending on how your playing it.
My good characters have people coming up to them giving them things.
Bad ones are always hearing snide comments like "thats locked for a reason"
or "I have my eye on you".
I have yet to fully map out the subway system. I've discovered different parts of it at different times.
But never really took it seriously, its almost like a separate game within the game. That sounds like a good job for my next character.
