I have already posted some suggestions for TU’s trading card system, but here I will post another different one, with much more content.
Card 1: Plaza
Card 2: Sweet Suites
Card 3: Ferris Wheel/Boardwalk
Card 4: Condo
Card 5: Condo Garden
Card 6: Accelerate Kart
Card 7: Minigolf Course
Card 8: Catsack
Badge levels:
Level 1: Tower Starter
Level 2: Boardwalk Explorer (pls dont make a pun out of this)
Level 3: Gamemode Adept
Level 4: Gamemode Professional
Level 5: Tower Veteran
Foil badge: Difference Maker (I was told naming badges by backer tiers might be offensive, this has to be discussed)
Badge logos:
Level 1: Darkgrey TU logo
Level 2: Lightgrey TU logo
Level 3: Purple TU logo
Level 4: Darkblue TU logo
Level 5: Standard TU logo
Foil badge: Golden TU logo with 3 stars sorted vertically on the highest tower (suggested previously)
Heard Mac doesn’t want it to be the TU logo, but rather what the player like about TU, so here’s an alternative:
Level 1: Train Station Blockout
Level 2: Accelerate logo or Jetpack
Level 3: Poseidon logo
Level 4: Catsack or Abstract Blockout of Condo Floorplan Editor
Level 5: Shining Catsack or Catsack
Foil badge: Golden Catsack
I don’t know really. These might be some shitty suggestions, but we’ll see what we might use.
