You ever hear of FFXI? That game has been running for 11 years. It has one data center for the whole planet. Game plays fine.
What you claimed are excuses are the realities of the internet.

Judging from Google results it does not play fine, the reality is basic physics and networking mean localised data centres give better performance, which is why many games go to the expense of having separate data centres, your excuses don't alter that fact.
