Do you want to be my new daddy?

huh? Of course. They need to make contracts, otherwise how would you determine which publisher is getting what amount of money from the Games Pass Revenue?
Obviously MS doesn't need to give permission for their own games, but why include every first party game from day one? They would receive less profit from their most recent game releases and they would have nothing more to add over the months to keep people subscribed to the service. Forza 5 could be included, I agree, but I guess it's coming within the next months.
Gears Ultimate, Halo 5 and Sunset Overdrive are still strong 1st party games to start the service.

How good are you with a lawnmower?

Most hardcore gamer will likely never subscribe to the service. It's aimed toward new Xbox One owners and casual gamers in general. It's one of those services that will get better over time. Games With Gold started out pretty weak, but over time got better and better.

Doubt it, it is an easy way to get a lot of achievements Hardcore gamers will get it =p.

Also games like DMC/mad max when they are on sale are like 9,99 euro on PS plus/gold same price to play the game for a month + 100-120 other games aswell. Give it a few months and see how it evolves.

Fair enough. I prefer not to have monthly fee's eat into my disposable income though. :P

If you have a small collection OR just bought a X1, I would recommend this service atleast for a few months. Also, get EA Access which has a lot of AAA content for a measly $30 a year.

The Xbox Pass is solid right now, but maybe they will add notable content every month. MS still has a bunch of their own games that could bolster the service.
