Just watched the OVA, found it hilarious that they completely flubbed a line of dialog. XD They said the whole Ally vs Betray nets a loss and gain of -2 to +2 when it's actually -2 to +3. Silly dubbers.
However I'm at a new level of '...holy crap' when they showed how the Ally/Betray system actually works. @_@ I thought you were actually in the same room with a single person doing a 1v1 thing. Not in as pairs having to guess what another pair is doing without actually seeing them.
So basically you're going to have to know who your opposing pair is, what their personality and mindsets are at base level, what their mentality at the moment is, how those individuals will likely react as a pair, what your partner's mindset is, how to convince your partner to go one way or the other, how your partner will react to your choice whether you agree or disagree with them, and how your opposition will react to your choice.
Also I'm still confused on a particular point of the Ambidex game. A lot of the translated material in promos so far has mentioned that you need to hit 9+ to escape. But not only did this trailer just say '9' but I think very, very early teaser material said that at some point someone 'has' to betray. So...is it 9+ or 9 on the nose to open that door? If it's 9+ then it seems like a lot of the tension would just be gone out of this. Everyone always allies until all pairs hit 10. But for all I know there could be a limited amount of times the AB Rooms open (if they only open 3 times then everyone would be stuck at 8). However if it's 9 on the nose it makes for a very complicated set of circumstances as Betrayal is now a requirement (even more so if the limited voting number theory applies).
I also have to wonder how this voting process registers since it seems to be team-based. If your partner hits Ally and you hit Betray what does the team vote count as? Is it in order of who hit the button first is paired with who hit the button on their side first (I.E: Your partner jams Ally without discussion but you hit Betray while their first button press is Betray and their second Ally; does that mean your partner gets the Ally - Betray while you get the Betray - Ally)? Is there a hierarchy system (I.E: Person with the most BP's vote counts for the team in a disagreement)? Too many questions about this game's nuances. >.< Hurry up Tuesday!
