Should I start from a template or from scratch?

Choose by where the user is, not by fashion. If customers search for you and order from any device, you need a website or web app. If they return often and you need notifications or the camera, a mobile app. If the work happens on the shop computer and the internet may drop, a Windows program. For entertainment, learning or an interactive campaign, a game that opens from a link.

A cashier program needs four things: a product list with prices, a fast sales screen that adds items and works out tax and totals, a printed receipt, and a report of the day's sales. You can buy a ready-made package, hire a developer, or describe what you want to an AI builder that builds it around your shop. Start with selling and receipts, then add stock and offers later.

You can make a game without coding in three ways: a game engine with visual tools where you drag objects and wire up rules, a ready template whose art and levels you change, or an AI builder where you describe the game in plain words and play it in the browser within minutes. Whichever you pick, start tiny: one character, one goal, one level.

Yes, this is called visual editing. Instead of explaining in words which element you mean, you click it in the preview and say what to change: the text, color, size, position, or hiding it. It solves the most tiring problem with AI builders, which is the tool changing something other than what you meant. Bigger changes to business logic are still clearer as a written description.
