Before this thread gets wildly off-topic *Ahem*, Resident Evil 2 remake, automatic win.
Back on hand, seeing as how Steele has the Codex and has been stated to play games on there on a couple of occasions and the fact that there is some big games tournament "coming soon" to Uveto, not to mention that Syri, Chrissy, Eimear and Fisianna are explicitly said to be gamers, then yeah, I would imagine that video games are a part of everyday life in the TiTS-verse. And with that in mind, I would also imagine that the companies that produce those games are at some stage going to want to show off their products at a major event.
TL;DR - there is more than likely a TiTS version of E3.
And now we wait for someone to try and write up that event.
