I'm turning 26 soon. I have a life, and so do my friends. When we meet; we dont sit down to play videogames. And for some reasons, I dont think that they want to buy a console and learn a very complicated fighting game like vf5 just to play with me.
Online support would provide me with a steady flow of competent players at any time of the day, forever. I'm not even going to buy the game since it wont be online, even if I know that it is a good game. I can't be arsed; especially for a 360 game; it would be a waste of time and money.
Also the whole 'sega says its impossible' thing is just bullshit and a byproduct of lazyness and lack of foresight; a bunch of AMATEURS managed to add ONLINE SUPPORT on kaillera for games ranging from mother****ing PACMAN to MARVEL VS CAPCOM 2 without having access to the source code, or anything, using mame and kaillera, and that for about A DECADE with more than decent results
Don't give me that bullshit, sega.
