The rumored stuff sounds good:
Perfect Dark reboot
Fable 4
FH4

They need more Japanese 3rd party support. Hopefully we'll truely see that this year with them getting games like Yakuza to launch on Xbox and some JRPGs. New IPs are also good.

Long to me is around 30 hour mark or games that have replay value. A few off top of my head:

The Witcher 3

Dragon Age Inquisition

Binding of Isaac

Fallout 4

Dishonored 2 (two playthroughs)

Assassin's Creed Origins (foury hour-ish)

Shadows of War (fourty hours-ish)

Watch Dogs 2 (around same)

Call of Duty annual games (couple hundred hours in mp)...yes I'm part of the problem.

Other times it's annoying, like ME: Andromeda, the most average and tedious game of the average. Mad Max also tedious to the end, even though it was around thirty hours.

I wish Xbox would adopt the Steam model and allow gifting games. I have friends who are too stubborn or cheap to play great indie titles and I'd love to be able to gift it to them. Shouldn't be that hard to figure out a way to send a redemption code to their inbox that's tied to their gamertag (if they're worried about resale, which is ridiculous I think).

We're a few years in now so there are a lot of great games to play. I can't even do this in order...

(BUT) Witcher 3 is #1
Binding of Isaac Rebirth
Doom
Forza Horizon 2 (haven't played 3 yet)
Gears 4
Diablo 3
Ori and the Blind Forest
Rare Replay
Rise of the Tomb Raider
Halo 5

But there's so many other good ones like Wolfenstein, Assassin's Creed Syndicate, Far Cry 4, Inside, Dragon Age etc.

Darksiders 2 is on sale for under $7 right now, go buy it.

I'm one of the few who are didn't think Last of Us was the best thing ever. And could never get over how much Ellie was just Ellen Page.

Rented Turbo Graphix 16, Genesis, N64 & PS1. I still remember the PS1 coming in a briefcase with foam cut out to fit all the pieces perfectly.

Just finished Hush, a pretty good thriller. I didn't like it as much as The Strangers but I did enjoy it.

It's weird, I didn't really like Firefly but I loved Serenity.

Yeah I did hear great things about the DLC, I should really make myself finish the game before I put it on the list.
