Play Mars: War Logs then. Technomancers do make an appearance there, even though you don't play as one. You can treat it as a side story in the same world.

Oh, I've played Mars: War Logs (though it's been a long time). I liked that one, as well, setting-wise and all. Sadly, the controls were still quite clunky (gave me motion-sickness the first time I tried it, I still remember that, haha). Technomancer was more refined in almost every aspect. But yes, another game in the same universe would be cool and I definitely want to revisit Mars: War Logs, too, one day!
