If a video game has the same developer but different publisher can they be played online together?

What I mean is lets say a video game comes out but in Europe its published by one company while the USA version in published by another one... could people who play online in the US play with those in Europe (has such a case ever existed)? Or will the online servers most likely be region locked because of different publishers?





Speaking of publishers who are the games online servers handled by? the developer or the publisher? The reason Im asking is because the game has a top notch developer and a top notch publisher in the EU but in the US its being published by the bargain bin/shovelware (seriously i think this is gonna be the first ever full priced $59.99 game they ever release) subsidiary of another top notch developer and because of this i dont see the online lasting as long I dont think the US publisher have teh funds to run and maintain and upkeep said online component for very long.. whereas the prequel to this game (which came out a year ago, was published by Sony.. whom i KNOW can afford its upkeep... the sequel however.. whom Sony is still publishing in EU but the opted out of bringing it to the US so another publisher picked it up).. so Im hoping the developers handle online and not the publisher.





Also how much power over the game does a publisher have? i.we could they exclude the online portion entirely if they choose? or make it so the save file from the first game doesnt transfer over to the second one? (like it does in the japanese and european versions)?|||well first things first, its usually the developers that have control over online play, regional servers, etc. most online games try to keep the people on EU servers to the EU side, but if there is no room left on the EU server, or your preferences cannot be met on the EU server it may put you on a US server until your preference can be met. As for the publisher power, yes the publisher can take out internet connectivity, but most times they don't because it helps sell the game faster. Also the transfer thing is more under the developer control, but don't be fooled because they can choose to have save files transfer in one region, and make it so files cannot transfer in other regions.
