I bought these and started DAO again a couple days ago. I had them on console before, but it was cheap enough to add to my Steam account. I loaded up a ton of mods this time. So far I'm having fun, but it crashes a lot, so I'm quick saving constantly. I'm not sure if the crashing is the game, my laptop, or the mods. I'm assuming its the mods and so far don't care enough to figure out which one(s). The good news is, I can go from desktop to loaded game in about 30 seconds, which is a nice change from modern games that take forever to load.
For those commenting on EA, if you buy on Steam you'll get a launcher, but you don't need the EA app to play (at least for DAO, I haven't gotten to the others yet). However, if you just don't want to give your $7 to EA (after Steam's cut), that's totally understandable.
