Abstract: 
Qualitative Choice Logic (QCL) is a framework for jointly dealing with truth and preferences. We develop the concept of degree-based validity by lifting a Hintikka-style semantic game [10] to a provability game. Strategies in the provability game are translated into proofs in a novel labeled sequent calculus where proofs come in degrees. Furthermore, we show that preferred models can be extracted from proofs.
