I quite liked Pilotwings Resort as a launch game but nothing more. It was good fun but felt very vanilla and soul-less after Pilotwings (SNES) and 64. The Wuhu Island setting was cool but I liked the SNES game's more real-world flight school/military setting far more.
Would still love to see Pilotwings NX, we've had two (soon to be three?) consoles now without an installment.
