Mario Party DS really is the best Mario Party
3D: Sunshine/Galaxy1
Kart: 64, 8, Wii
SMB: New Super Mario Bros
Sports: Strikers Charged, Tennis 64

The iconic Paper Mario.
Mario Kart Double Dash, Mario Party 3, Super Mario Galaxy 2, Super Mario 64, and Mario and Luigi: Bowser's Inside Story are great too.

Your taste I never really got into Galaxy or Strikers but I agree with everything else you said! Tennis 64 and Mario Party DS slayed lives

Mario Party DS was the game that made me so fascinated with Peach. Her poise and eternal youth >>>> the other princesses
It doesn't get better than the boss battles, story mode and Toadette's music board

Tennis 64 had me non stop trying to fill out that player chart and I don't think I ever did

Super Mario World (SNES) is one of the greatest games of all-time. It is far and away my favorite Mario game.

I only use Kart sometimes so this one, I guess.

Super Mario Galaxy.

Paper Mario: The Thousand Year-Old Door >>

Is Sunshine really that good. Its one of the few Mario games I've never played

New Super Mario Bros >>>>>

Yes. It's so underrated and it's the most risky Mario game ever. It plays so different than all the others and it is so nostalgic for late 90s/early 2000s adventure-platformers.

No game in history will ever beat out Mario 3. Best game ever!

Yes. It's incredible. So mad that they didn't make a sequel for Wii

Super Mario 64, tbh

Super Mario Galaxy
