I also have tightly packed teeth and can barely use interdental brushes on just some of them. What works well however are dental floss sticks, you can get them with pretty thin floss(es?) and they're way easier to use than plain floss.
Ace Combat X, it was my first game of the series and got me hooked. It's too bad the branching story paths aren't really a thing in the other games except AC3 (the best entry in the series imo)
Nowadays my psp is sadly broken, the screen is showing it's individual pixel lines with some offset or something, but hey emulation is really easy
