Machine Man 1992 said:
Dark Souls.
Just a cavalcade of broke-ass design and completely wrong headed approaches to difficulty. I wouldn't have put this here, but the sheer number of people who like this game and rush to rabid defense of it just makes me hate it and everything it stands for.
Funny, your idea of worst, is my idea of best. You do come off as a "stop liking what I don't" sort though because of the bolded part.
Don't know what you're talking about with regards to "broken design and wrong approaches to difficulty" as I believe the design was solid (level design was among the best ever made period) and the approach to difficulty was fantastic (you and the enemy being squishy; a reason to not die; chance to still recover; rewards patient gameplay).
Frankly the best games of this gen, IMO are: Dark Souls, Demon's Souls and Valkyria Chronicles.
OP:
Of the games I played this gen? Dragon Age: Origins: I tend to not play too many stinkers though. Eerily simlar to Machine Man 1992, I did hear good things about DA:O, enough to get me interested. But goddam that game was a let down (played on PS3). The combat was a clusterfuck; the programmable AI tactics straight up didn't work; the game could be easily won with AoE magic spam; the story was a LOTR rip-off; the characters were completely unlikeable - especially bitchy Morrigan and emo Allistair; and the colours - from dark brown to light brown... blugh.
But the true worst game I've ever played - E.T. for the Atari. I was kid - maybe 8 or 9 years old when I played it back in the '80s. With little other games to play and E.T. being my favourite movie at that time, I wanted to like it - but it was just terrible. My friend and I quickly went back to Return of the Jedi (Atari) as that at least was pretty fun.
