One of the minor issues I have with the interface of GoIO is how as a game starts you cannot exit back to the main menu without waiting for the match to load. You have to physically quit the game. This is a waste of valuable time, as that quick loadout change you need could be performed while others load, all but eliminating the chances of missing the opening salvoes. There is also the case of one failing to leave the lobby as they are enwrapped in conversation, although I imagine inaction deserves some punishment. That, and due to my incompetence I always press the damn 'Exit Game' button accidentally.
On a side note, beware the false button. It states 'Back to lobby', but alas it kicks me right out the game. This is probably due to my OS, Macintosh, and in such a case is an irrelevant quip.
On a side note to the side note, I'm enjoying writing posts in such an odd fashion. I'll either go even more bizarre or tone it down a touch. That, and I doubt many will care for this issue, simply as it is easily avoidable and rather unimportant.
