What to play?

The Darkness is short but fun.

Bioshock maaayn, might be a pain, but worth it.

Another vote for Bioshock...

Bioshock. Thanks for Batman.

I'll go for Dragon Age for a longer experience

Darkness II. Doesn't take too long to get through.

If you want something different you may want to try The Cat Lady, such a good game. If not, maybe it's time to try Akrham Asylum, one of my favourites of its generation

Play that Trine 2 or Mark of the Ninja in your game library. :D

Or Batman. :P

The Darkness II, just because of its' wonderfully dark story and theme :D

Never played 1 or 5 but I can say Dragon Age: Origins is one of my favourite games! Played through it probably 6 times though with Ult. edition you'll probably spend around 40-50 hours on the main quest and maybe another 15 to 20 for all the dlc and expansion but can't quite remember so may be longer or shorter :p
Batman and Bioshock both took me around 20 hours to beat I think granted I KNOW I could have beaten Bioshock in around 10 to 15 hours I just took my time with it and it also starts dragging on in the last quarter in my opinion but still a great game. Batman was a blast the whole way through and I would say probably the best choice there if you don't have tons of time to play DA:O lol

bioshock
