This article applies the OPF (Objective, Process, Feedback) model to analyze common issues in turn-based RPGs, such as monotonous objectives, tedious combat, and lack of surprise. It recommends diversifying player goals (e.g., collection, crafting, strategy), reducing ineffective combat time (e.g., skip, speed-up, visible enemies), enriching battle strategies (e.g., terrain and weather interactions), and introducing unexpected events (e.g., random encounters, branching dialogues). Examples from games like 'Pokémon', 'Divinity: Original Sin', and 'Xuan-Yuan Sword' illustrate how these methods enhance positive feedback loops and player engagement.
