RoFishy

The real thing here is you should prioritize "individual and interactions" over the processes and tools. This means that sometimes OOP is the right answer, sometimes it's a ton of tiny scripts scattered throughout the game. Sometimes it's functional programming. Sometimes it's both. This also goes for toolchian. Sometimes Git + Rojo is the right answer. Sometimes it's Filesync or Roblox Studio script editor. And it works for UI frameworks too. Sometimes React is great, sometimes it's Blend or Fusion. Sometimes it's templated UI. Don't talk about technology, processes or tools. Talk about how individuals on your team interact with each other and then pick a tool, process, or technology that leads to good interactions.
