The prime motivation for theoretical studies of large-N gauge theories is to improve our non-perturbative understanding of 'low/moderate'-N physical gauge theories such as QCD. This can be accomplished in a phenomenological framework where one uses the aforementioned theoretical features of large-N theories (e.g. factorization of correlation functions, volume/temperature independence, suppression of fundamental fermions, orientifold projections, simplification of baryon structure etc.) to make qualitative and quantitative predictions in physically relevant cases. This phenomenological approach has been recently applied to several areas of research that, in addition to those mentioned in the above sections, include various properties of the QCD baryon sector, the thermodynamics of QCD at nonzero temperature and density, and chiral dynamics.
