Anything from the PC Gaming Show if they’re doing that again, you never know what’s going to come out of that. BattleTech was a pleasant surprise a couple of years ago. Necrobarista seems interesting, even if they’ve gone radio silent for a while now. MechwWarrior 5 would be amazing and it seems close to gold. A port of Yakuza would be really nice.
There’s also Valve, and before you start snarking, there’s a high likelihood that Valve will be in E3 soon. Maybe not this year but soon, they started making games again, and no not just VR bullshit. With Artifact, their new acquisition of Firewatch studio, their new office and the new hiring website, Valve is back in making games. No HL3 tho, it’s financially stupid to release it at this point.
