Yeah some of the side plots were nicely done, although I hated how some of them made me use the slow ass subway back and forth constantly. That could just be attributed to Prague being terribly designed in my opinion.
I just don't think the crit path --the thing that is supposed to be the primary drive and motivation to move forward-- is engaging enough, and besides side missions Prague has very little to offer.
The apartheid backdrop they used wasn't anywhere nearly as interesting as the morally grey issue of human augmentation like in DX:HR, and the illuminati plot had no mystery and went nowhere.
