The minigames were kind of OK, though it sucked that everyone got Mini Stars, no matter if they were in last place or won. However, what greatly sucked about it was that you actually could skip your chance at getting Mini Stars if luck wasn't on your side. How? Well, if we take a look at all the previous
Mario Party-titles (minus
Mario Party Advance, of course), we see that, should an opponent pass the Star Space and not have enough coins to purchase the Power Star, that opponent just couldn't obtain the Star on that turn, still allowing you to get it when it was your turn. And because the boards in
Mario Party 9 aren't circular, what said in the last sentence is obviously not applicable on any board you'll ever play in
Mario Party 9, thereby increasing the luck-factor by a huge amount. And if we look back to the previous
Mario Party-titles again (and of course while continuing to not count
Mario Party Advance), we see that, when you move,
only you move. In comparison with
Mario Party 9's system, we see that that is yet again not the case; when someone hits the Dice Block, everyone moves. That means that not only are you locked out on getting Mini Stars, but you are additionally required to witness your opponents gaining them as you sit out on them everything based on luck, of course.

R: Minigames were OK, the boards sucked.
