I know using the console blocks achievements, but do mods do that, too

That's all!

Don't think so. Mods just add or change the content of the game like a DLC would

I tested various mods to figure this out, these;

 

No-ban at casinos (this does for obvious reasons block out the 1 achievement where you have to be banned from the strip's casinos, but turning the mod off returned it to normal state, so just make sure to get banned from the casinos before you)

Higher bets/wins at casinos

Addperk (1 every level)

8000 carryweight

No karma-loss from stealing.

 

And I've been gaining achievements still. I don't really see any of these mods as cheating tbh, except for the addperk one maybe, so I don't really consider myself a cheater. I loved to mess around with cheats in Fallout 3, and I definitely will after I get through the steam achievements (I don't know why, I just have a compulsive urge to do so)

 

Bottomline? Mods do not disable achievements, for now.

I was just looking for an answer to this. I played through Fallout 3 with a few mods (hair & body stuff mostly and the weight limit increaser) and I still earned achievements. I was worried that this game using Steam instead of that horrible Games For Windows Live junk might have changed that somehow. I want to do a run through on hardcore but with some cosmetic changes as well as increased weight allowance and don't want to find out that I missed out on that Hardcore achievement because of it.
