I like most immersive sim games. However, the market does not seem to like them. They are very hard to make and get right, but the RoI is mostly cult following.

If you liked Deus Ex, you might also like Dishonored and Prey.

PS: I would love to build an immersive sim if I get enough time, but I know for sure that it would just be a labour of love, like a painting which may or may not sell.
