Losing the game vs Winning the Game

[FTW]

Suppose you have a Platinum Angel out in a multiplayer variant where each player has different allies and enemies (e.g. Pentagram). Suppose one of your allies plays some combo that results in the clause "Win the game". Platinum Angel would not stop this, since the player is not an "opponent". Yet you also cannot "lose the game". What happens? Who wins?

For example, in Pentagram, would the other 3 players just lose, making it a draw between you and your ally since each of you lost both your opponents simultaneously? Or would his "win the game" clause only make his 2 opponents "lose", making him win (and you effectively "lose" by default, which should be impossible with Platinum Angel in a multiplayer game)?

What if both you and his other ally have a Platinum Angel? Would just his 2 opponents lose, causing him to win and neither of the 2 Platinum Angel holders to win?

Basically, 2 questions:
1) is the "win the game" clause modified by "each other player loses the game" or "each opponent loses the game" in such a multiplayer variant
2) in such a multiplayer variant, is it possible to "lose" because an ally has met the victory condition, even if you have a Platinum Angel, just because yours is not also met? or does it become a draw?

This is not an officially supported format by wotc. As such, there are no rules governing the questions you are asking. Even formats with some level of support, such as 2-headed giant have run into rules snares that have been dealt with over time. In your case, there is not even that frame work though. You guys are going to have to come up with your own solutions to these dilemmas. In this case, you will have to define who is an opponent. I would argue that every other player is your opponent in that scenario, if for no other reason than it is the only way to make Platinum Angel make any sense.

All I know is I just lost the game.

You can read the comprehensive official multiplayer rules here: http://yawgatog.com/resources/magic-rules/#R800

The one that might be most relevant to your question:
800.7. In a multiplayer game not using the limited range of influence option (see rule 801), if an effect states that a player wins the game, all of that player's opponents lose the game instead.

As Finn said though, there isn't official support for a format like "pentagram". Whoever was formalizing the rules for the format would have to figure out how they wanted things to work within the official multiplayer rules.

Ok, thanks.

Yeah, I was aware of that one comp rule for multiplayer in general. But Pentagram is a bizarre format where you have players that are not "opponents" (we play where you cannot target them with things that say "target opponent" or "each opponent", you can use cards that effect allies on them, and of course you cannot attack them) yet you don't necessarily win the game when they win, so we were not sure how to apply that replacement effect. Which players would it make lose? Every other player? Or just your two "opponents"? Pentagram also has a specific victory condition: you "win" when your two opponents have both lost the game. Does Platinum Angel see failing to meet the victory condition when someone else has as "losing the game" and stop it from happening? Or is it different since you have not explicitly lost by Magic game rules? Or is Platinum Angel unable to stop him from "winning" (since he is not an opponent) and merely stop you from "losing", resulting a win for him and a 1-way draw for you (since the game would be over)???

These are questions I was hoping other players of the format had resolved. Anyway, thanks for the responses. We'll have to vote on something.
