Some people don't seem to realize how amazing it will be to have dedicated servers for EVERY multiplayer game. So I will try to clear up the confusion.
Current servers are person to person (P2P). You would be the host and I join your game. Most games pick a random host. If the host in the P2P has a crappy connection, everyone in the game sees lag, hit detection, and connection problems. You also see host migration with this setup. If the host leaves, the game pauses, finds a new host, and then continues playing again. This is how most online games work like COD, Halo and most other games.
In dedicated servers like BF3, the server is the host. You join and leave that server without interrupting anyone in the game, along with no host migration. If you have a crappy connection it does not effect everyone in the game. Only YOU see the lag. Dedicated servers are THE best online experience you can possibly get but it is very rare for games to have dedicated servers.
This has never happened. Not on PC, not on the PS3, not on 360. To have dedicated servers for EVERY multiplayer game would be an innovative revolution for gaming. Beyond incredible.
That's an empty promise. Clear as water for anyone that has experience playing pc games.
1.- Dedicated servers are all about location. Lag mainly revolves around the distance between the player and the server. There's absolutely no way the Xbox One will cover the US with enough dedicated servers for each game, let alone worldwide. On that matter, isn't it funny that the whole presentation and console itself revolves around the US but forgets where practically half 360's sales came from?
2.- Reliability and support issues. If the server is down, whether temporarily or permanently (lets say two years from release), does that mean I cannot play online?. If the server is laggy, for example with PL, do I have to have an awful online playing experience?
Maintaining good and lots of dedicated servers is very, very expensive and it requires people to be in constant charge of them. Do not think there will be a good dedicated server near your location nor that they will stay forever.
3.- Connection and ISP problems. 10 years ago this didn't matter much, but nowadays companies do not prioritize online gaming, thus there will be issues with certain internet providers and certain server locations. What that means is if your ISP gets 150 ping to a server that's right next door (yep, welcome to 2013's routing) then you have no choice but to play on a server that's thousands of miles away from you, therefore no choice but to play with 150 ping or more.
4.- Back to finding servers manually once again, whether the console still features p2p gaming as an option or not. Not the greatest idea on this day and age, though an alternative is addressed at 6.- specifically for dedicated servers.
5.- Practically all PC games that support dedicated servers have them, uploaded by players (individuals) and not by the game's developer (unless certain exceptions on this last note). Problem on unpopular ones is described on 1.-.
That means it's not a 'rare' thing on PCs (I can find servers in games games that are older than lots of GTP users, in any location in the world), nor a 'revolution beyond incredible' (way too farfetched), though you have to search for them (IPs). This also adds a second point, now applicable to this case: the announced Xbox One dedicated servers will be uploaded by microsoft, considering there's no way they will take the risk of enabling people or game devs to upload their own, for various reasons such as quality of service and expenses.
6.- Games have to be made taking into account dedicated servers, otherwise it'll end up in having lots of them empty due to how manually searching for IPs work (players way too spread and people don't join empty servers). Think of this as how black ops 2 does it in p2p's case, which is very well made but requires developers spending lots of time and money to implement it.
7.- In the end what I want to say is p2p will continue to be the standard on the Xbox One. Simple as that, to the point I can assure you they will still feature p2p gaming and that p2p gaming is optimal for console gaming in 2013 up to the next gen (ps5). If they were so sure they would remove it entirely, for the so called superior alternative that consists of dedicated servers uploaded and controlled by one company. As for the second affirmation, actually I barely touched some of the issues, because I could think of twice more as crucial as the mentioned ones.
edit: Same goes to TV connectivity: it's technically not possible to fulfill that promise as well as it sounds. Anyone that has experience on that matter knows the Xbox One integration with the current TV boxes will be awful, or at least not good enough to make people use it instead of just relying on your current box alone. Also consider this will only work with cable providers in the US.
Microsoft's focus here is simply wrong and buyers will pay for the two said features (that won't work). If anything, watching the PS4 presentation is actually refreshing, as weird as it sounds being it from Sony, and on paper the PS4 utterly destroys the Xbox One in every single point that matters for both casual and hardcore gamers, though we don't know prices yet.
edit2: sorry for editing this post this much. If anyone wants to quote it please do it entirely, with the modifications. Finished now.
