For me it would've had to have been either the day Daisy's announced for MK7, or when Rosalina was announced for 3D World, Smash, and MK8 in like the timespan of 3 months XP.
What was the most exciting day for you (On forum or on site)?
- Thread starter ImpaDude
- Start date
The Nintendo Direct where Rosalina was revealed for MP10.
The day Rosalina was confirmed in Smash 
I CRIED XD
I CRIED XD
Transition from SMPSF to MPL and plenty of other days in the shoutbox joking around.
The day when I got to play an online session of mario party with three other people(brady23, Spongyoshi, and landers).
