I am a very, VERY creative person. Whatever I do, I just mostly think of an idea for a map. Here what I came up with so far.
Monster Legends Map for Mario Party 1 (Based off of the Monster Legends app)

Checkers Map for Mario Party 3

Space Land Map for Mario Party 1 (from Mario Party 2)

Gravity Falls Map for Mario Party 1

Spiral Mountain Map for Mario Party 1 (from Banjo-Kazooie)

Vanoss Mask Map for Mario Party 1 (cause I love Vanoss and made this for fun.)

Green Hill Zone Map for Mario Party 1 (Map made based on Sonic 3D. I added the Sonic Advance Sprites)

MTT Resort Map for Mario Party 1 (from Undertale cause Snowdin was impossible to make on a chromebook without paint.)

Bowser Land Map for Mario Party 1 (from Mario Party 2 again)

Outworld for Mario Party 1 (from Mortal Kombat Deception)

Fazbear Pizzeria for Mario Party 1 (from Five Nights at Freddy's)
Slot Car Derby for Mario Party 3 (from Mario Party 2. Sorry if I can remove the scoreboard, It was impossible without paint.)

And lastly
The Moon for Mario Party 1 (This one I made from scrap as shown from the badly drawn lines.)

Right now cause of the no spam rule, I'm currently waiting for the Monster Legends map to be approved before I put the next map up. Feel free to comment which one to put up next.

If you like to try them out, I do got a link right here. Enjoy!
