The uncertain future of games like Deus Ex and Dishonored

Warren Spector is stuck in Prey. The director of Deus Ex, who has worked on many games since labeled "immersive sims"—in fact, he coined the term ina post-mortem of Deus Ex —has been playing the modern games inspired by classics like Thief and System Shock. But he hasn't finished Prey yet. Or, as he puts it: "The crew quarters are kicking my butt."

He's enjoying it though, just as he enjoyed the other recent immersive sim from Arkane Studios, Dishonored 2. "I thought they were both excellent examples of what I think of when I say 'immersive sim,'" Spector says. "They removed barriers to belief that I was in another world and they let me approach problems as problems, rather than as puzzles. I'm really glad Arkane exists and that they're so committed to the genre. Without them I'd have fewer games to play!"

Spector's not the only one who'd mourn their loss. Arkane is still around, but there's this uneasy feeling in the air that there's now some reason to worry. Not about Arkane, necessarily, but the immersive sim in general, this genre held up as the shining example of PC gaming at its most smartest and most complex. None of the last three big-budget immersive sims—Prey, Dishonored 2, and Eidos Montreal’s Deus Ex: Mankind Divided—have broken a million sales on Steam.

It's always been a niche genre, defined by player freedom, environmental storytelling, and a lot of reading diary entries. How long can they be propped up by the fact that some designers really like making them?

Arkane's Prey is the latest in the System Shock lineage.

Don't call it a comeback

In the 1990s and early 2000s immersive sims seemed like the future, an obvious extension of what 3D spaces and believable physics and improving AI could do when working together. But they rarely sold well. When Ion Storm’s third Thief and second Deus Ex game flopped, the studio closed. Looking Glass Studios, responsible for System Shock, Ultima Underworld, and the first two Thief games, was already gone. The immersive sim went into hibernation for years.

Despite the love and praise for games like Deus Ex, they're not easy to sell to players. Jean-François Dugas, executive director of the Deus Ex franchise at its current owners Eidos Montreal, says it can be tough even convincing people to make games that let players deviate from the critical path.

"You need to realize and accept that you will build a ton of material that a good part of your audience will miss," he says. "Since you are building possibilities through game mechanics and narrative scenarios, you know that you might not be able to bring all the pieces to the quality level you would like. You have to rely on the effect of the sum of the parts to transcend it all. The GTA series is a great example of that. When you look at all the pieces individually, they’re not the best in class but what they offer their audience when combined is unparalleled. After that, there is a big effort required to convince your team and upper management that spending money on things that many players will not see is a good idea," he says with a laugh.

Deus Ex's Hong Kong, richly detailed and packed with things to discover.

Spector disagrees with the notion that immersive sims are harder to convince publishers on. "Honestly, I haven't really noticed any particular challenge.
