How badly glitched is the game?

I've noticed a few comments on help forums about game bugs that ruin quests and that were never sorted out by EA. I bought this game cheap out of curiosity. I don't want to get too involved if, like Sims 3, it takes a heap of mods to run, or has too many bugs that make quests impossible. So how bad is it?

The game requires a few patches but I assume if you got it through Origin then it should be patched. There are less than a handful of quests that seem to have been left bugged. I can't remember exactly which ones those are. But if you bought the disc and not through Origin the game does need the two patches it got besides the quests that didn't get fixed.
