- Yes. All game data is stored on disk for the game to be able to run, including models, map files, etc.
- Theoretically, yes, but in practice, no. In-game items reuploaded onto the workshop are removed. This isn’t including the time it would take to extract each needed model and assemble the map file into an individual model ready for upload, which may/may not be a time-consuming process (I don’t dabble with that sort of stuff, so not sure).
From the Rules section of the Workshop Manual:
Do not upload Tower Unite game content / items that have not been modified.
I suppose you could change things up a bit and it would technically not be against the rules, but I’d think that uploading an entire condo would be close enough to allow for the item’s removal anyways.
From the EULA:
You may not decompile, modify, reverse engineer, publicly display, prepare derivative works based on TU, disassemble, or otherwise reproduce TU.
This isn’t including things like performance issues, proper collision, lighting, etc. that arise from workshop limitations.
TL;DR: You can, but it’s against the rules, and may not be a good idea anyways.
