Where to buy Deus Ex Human Revolution non-DC?

lol :D
ok Sleeping dogs also had high-res textures added and stuff so is it a different game? No, it's just a regular GOTY except it's "the definitive edition" or "director's cut"
and seriously have you played it? The boss fights in DC are pretty much the same thing except now they added some turrets in the Barret fight, that's it. Anyway, the point is that no matter how you perceive the game as different or not, it still doesn't make any sense to look for the original release.

you also get cards for steam,the original version doesn't drop any cards

It was ported from the unpatched version of the original game. The original version did have all the same issues as the DC at one point.

It is better(even though I haven't played it but I've read the differences from the forums). I've always had the non-DC version so the biggest difference I'd say would be the bosses, I think.

Not that guy - but the way I understand it the DC has a documentary, commentary and other stuff that doesn't affect gameplay. It has the Missing Link DLC and modified boss fights, which is maybe most important as those were pretty unbalanced for certain character builds in the original and could make progress very difficult depending on your choices. But it may well also make no difference depending on your playstyle.

Unfortunately the DC is also a lot buggier. I heard it was based on an earlier unpatched build of the game. Which sounds crazy but makes sense having played them.

Pros and cons for both - it is your call.

Ok, if you want the vanilla version go to trades (Steamtrades), some people sell it cheap, for like 1TF2 key.
