Played them all, the old ones were great for their time but not good now as far as mechanics go. My favorite game is from 1999, but tons of great games have come that evolve past that game in tons of ways, just they weren't as meaningful at their time of release as that game was at that time.

I played Invisible War first in 2005. Then I played Human Revolution in 2011. I like it so much that I bought the original game a few months later and then I went back and played HR. The gameplay, augmentation, and exploration is like the original, just updated. Although I think the plot, writing, and atmosphere were much better in the original. Eidos Montreal did a good job of carrying the torch. Now if they could make a more dystopian and plot twist filled story and add a better main character than Jensen, that would be great.

Having played the original in 2000 and now playing these new one, I still go back to the original. The latests ones don't have the lasting appeal.

Ive gone back to replay the orginal many times and even invisible war, not so much with the newer ones.

The Story in DX is miles better than the new ones.
